Probably so.

ST's HAL system is hideous for sure.

Their regular old .h file for registers is OK.

I use the HAL only for initialization from their CubeMX tool then it's non-HAL the rest of the way.

C32... Oops!

On the main board I would solder the wires to C36 and then run the wires on the board to C35 and RTV them down in between C35 & C36

That got inspected by the VOA machine, with a manual followup. It's connected.

So far, every one of these 250-watt class-D amps has worked when we powered them up.

Or maybe strip the wire long and solder to all the caps. That wire is #16 but could be 18 or 20.

But what he did would work OK. We don't expect vibration.

Another vote for this.

The pin mapping is so irregular that a computer tool is a great help.

It's probably radiating more than it needs to. Just one full twist in the wires would shrink that.

At 400 Hz in a metal box, radiation is not a concern.

Actually, the load is a chopping shunt regulator that runs around 30 KHz. That's going to scream.

What's hideous about it? STM32 in particular is complicated enough that most people will not find it economical to roll their own HAL.

What's an example of something that would hose you if you used the HAL API?
