With more and more players expecting emoji support in text entry boxes, more games are starting to ship with full unicode support. Also I've noticed optional ligatures that OpenType supports have become a big style thing in certain game genres/by certain studios. Harfbuzz's "Old MIT" license shows up more often in the credits of games and game engines.

I don't know if that's a good reason to push to standardize controller glyphs to Unicode, though.

(ETA: Plus the other obvious reason more games and game engines are bringing in full Unicode support is localization, especially for Arabic and CJK. We're a bit past the point where AAA games only feel a need to support EFIGS. The Middle East and Asia are huge markets, especially for mobile games.)
