Android is a different beast since OEMs highly customize the UX. Samsung could easily make a horrible liquid glass ripoff and stick it on Android without Google doing anything.
Most of Google's work on Android seems to be around making smaller changes for the UX and bigger internal changes (splitting up the OS so individual parts can be updated without the OEM involvement, security changes, etc).
