I have no reason to think the user who requested LGR support
for FiraSans intends to use xelatex or lualatex. Or that
hyphenation is an issue for him; the only example I've
been sent involved using sans-serif Greek letters in math
formulas. At least two other font packages support LGR
encoding, which seems to be a de facto standard.

Using the type1 font to reproduce whatever pdflatex does
seems like a satisfactory approach in the font package for
users who might naively switch to xelatex or lualatex and
expect comparable output. "Nonsensical" hyphenation is the
user's problem, not mine.
