The design of any library for a microcontroller and an "equivalent" for general end user application is going to be different in pretty much every major design point. I'm not sure how this is any more relevant to fmt than it is just general complaining out in the open.

The code for an algorithm like Dragonbox or Dragon4 alone is already blowing your size budget, so the "optional" stuff doesn't really matter. And that's 1 of like 20 features people want.
