partly its because it just doesnt matter EXACTLY what font. you might give Elon's rebranding of Twitter to the Unicode X glyph as a most famous recent exemplar application of this perspective -- plus it saves money on custom font crafting or analysis work.

two: there really are a certain set of traits an ideal font should have and only a subset of all possible fonts have them. so just pick one of them, dammit -- Janet! -- and move on.
