I think a lot of nerds on here a going to have to take a hit to their convenience and start evaluating alternative mobile OSs as daily drivers instead of crying about iOS and Google's Android.
I'm interested to hear your results!
To displace Apple and Google these kind of changes need grassroots support for those alternative platforms to get better (and to get funding) so they need a lot more users and developers.
We've done this before (Microsoft, Internet Explorer) and can do it again!
(I've been using #SailfishOS since 2013 and #GrapheneOS for years.
Happy to help with questions.)
