Not sure if it makes much difference, I sometiems double check with omh meter for small things I build anyway. For large production quantities it may save a fraction of a cent per item perhaps thousands of dollars if millions are made. Repair shops SHOULD have the right drawings. Re-use? I think not.
Environmental reasons? Is white ink toxic? We use KOA or Vishay anyway. doesnt really affect us.

** Speaking as a service tech - it sucks big time.Any maker who ever wanted to prevent copying or repairs by anyone but a chosen few knows that all you have to do is remove the part numbers from all the semiconductors after manufacture.
Thankfully till now only a tiny, paranoid few have ever done so.
SMD products are hard enough to service even with fully marked components, this move will make it impossible except with the full co-operation of the makers and their overseas agents.

Crud! To date I've been trying to buy Yageo specifically small production run items specifically because they are marked.
@#$%!
You can get close to the resistance of a lot of parts by measuring them in-circuit, but it's often only close and sometimes not close at all.

Folks are doing fine with the smaller form factors, which have never been marked, so the thought is why do we need any continued marking on the larger form factors?
The intelligent among us will survive just fine.
Might as well strip markings off all the other parts too, for the same reasons. Who needs to know what parts are which? They're all exactly the same, right?
What's all this part-marking stuff anyhow?

With all this in mind,
is there a web page with SMD markings to real part numbers ??
I have some parts that I misplaced the data sheet...... ;-)

Maybe with all that ever larger integration we could have speaking capacitors, SMD caps that vibrate a la Joerg and say: Hi I am an 805 10 nano Farad, I need replacing, my dielectric is failing, BEEP BEEP BEEP. Radio tags? Ah! Wireless of course: Hi am am the 805 on your left ...
I think the gist is to keep them sorted in your workshop, that is what I do, and no problems, sometimes I measure one...
Parts could communicate among themselves too: Hi, I am the 805 in series with you, can you adjust down a bit my resistance is going up? mmm programmabe SMD resistors and capacitors... Anyways who needs all that stuff, soon everything will be integrated, only need a clock. And it would fall out anyways due to no-lead soldering and short because of whiskers...

Maybe they will start using color code.

In many ways, resistors and capacitor markings are even more important. If you mix up the feeders of other parts the guy watching the reflow oven has a chance of find a big problem early in the process. ;-) Not so much with resistors and caps.
I never look at them (resistors and caps) but I'd think QC could use the information.
I had a $350 device fail, which I sent back for repair. They claim it's "not repairable". Head office is in Taipei, service depot in the US. I bet it's nothing that would take a decent service tech more than
15 minutes to fix- it works for a while then cuts out (probably a power supply fault of some kind causing regulator shutdown). I had it returned so I could look at it further.Maybe I should trace out the circuit and post interesting bits of it, since they don't seem willing to repair their stuff or supply schematics. It's an RTD->Ethernet module.

Sounds thermal to me, bit of cold spray bring it back? Use a mask to find the component, hope it is no chip, and if it is some recognizable type number...
Time counts too, no use spending many hours on something worth nothing.
