LS/HCT/etc. logic familes

Is LS logic still at all relevant for new designs? Is HCT logic still at all relevant for new designs? Is the 74xx/4000-whatever series still at all relevant for new designs? Do you use them at all regularly in your work, or have you moved on to more modern families (or Just Use A PIC)? They still have many "LS" series ICs available in fairly large quantities at the usual distributors, in SMD packages even. So I assume someone must use 'em for something. Inquiring minds want to know...

IIRC 74C (not HC) also had a supply range like 4000.

Yes, but they are gone.
