There's no real reason not to keep these around as extra options, unless you don't want to or worry that there will be way too many options once we fully slice FA?

I'd imagine possibly using this composer UI for Phame (and maybe even Users?) in the future, so having even more variety seems sort of nice. Although it could get overwhelming if you have 2000 options to pick from, but we could do grouping or something eventually.

(That said, I don't think we use the actual sprite or have any plans to do so, nor the 1x images, since we always compose PNGs from the sources.)

I roughly plan to land a handful of fa equivalent. I just didn't want to overload this diff. "All" fa is a bit overkill unless its a typeahead.

can I move these out of /sprite/ then?

Yeah, just fix the path in IconComposerBuiltinFile too.

We were using the sprite sheet in the file composer, so I re-wrote that as fonts instead.

Ah, sure. We can swap that for composed builtins too if we do want to add non-FA images eventually.

Honestly haven't found setting project images to be very helpful.

I think it would be more useful if we were larger. This one's pretty good:

WMF has some really good ones, too:

hahaha

Maybe we can go to 100px then (200px retina).
