Some input as an Android dev: the API level stuff is not nearly as much as a problem as it was some years ago. Nowadays you can easily require 23 or 25 (see https://apilevels.com/ https://apilevels.com/) - since 23, there were definitely some changes, but not terribly big ones that are really painful. I'm rather getting a headache with new form factors (window insets, foldables, tablets being revived). Also: Usually all google libs are backwards compatible to 21. The new ui system (Compose) just gets shipped with the app itself, increasing download/installation size. Apple does not do this afaik, they require a recent minimum OS version for compose ui.
