"Phillips" is a definitive callout for the drive.
I've been spec'ing industrial quality Phillips
machine screws for 25 years and never seen one
that didn't fit the driver tight.

Err.... actually, Philips is a tradename, and it's licensed
so there's probably some genuine standards commitment
there. Philips markings on a screwdriver used to mean
some assurance of quality (maybe still does).

I can show you any number of unambitious and
acceptable assembly drawings and bills of
material that call out Philips screws.

Tradename doesn't matter. I can call out a
Philips screw just as I can call out Delrin
or or Meehanite as a material.

Or maybe I've missed your point...
