It is pretty widespread, I think.

So a quart now is two typographical points?  Sorry, that does not
sound right.

Anyway, I think it unreasonable to work with gal, qt, but then require
"pint".  If gal and qt are the usual abbreviations, then I think the
normally used abbreviation for pint should also be used.  Sure, TeX
users would prefer to have pt and bp, but I don't think at the price
of making the Imperial system inconsistent.
