Even if they manage to get big players like Spotify to develop apps for them, a lot of people - at least on the Android side - have smaller, niche apps for audiobooks and podcasts that would never bother to port their apps to GM services. Heck, even Apple Music and YouTube Music wouldn’t bother. I smell an upcoming BOGO deal on their overstocked dealerships, just before they get another bailout check.
If you have a Samsung, Goodlock can edit the share sheet down to the very app, as well as favorite contacts. I’ve also been using LinkSheet (available on F-Droid) with ClearURL to open links notorious for nasty redirects, and it may help with some of these features you’re looking for.
