Sure, it's no change for self hosters currently, but it's one more step in moving towards a more closed platform overall. I do hope more FOSS client apps end up getting made sometime soon. I've been using Keyguard on Android for some time, which means the recent several breaking changes in the Bitwarden apps to the Vaultwarden backend haven't hit me as hard, but I do still use the official apps for my laptop and desktop and Keyguard isnt fully FOSS, of course. I'd love to see some forks or brand new apps one of these days that are actually fully FOSS for both mobile and browsers. I've thought about doing some myself, but I have too many other projects and I also don't have a MAC or want to pay the fees to make an iPhone version. And I abandoned my Android Developer account when they started the identity nonsense, so none of my apps are on the official store anymore and Fdroid and similar may not be viable soon, so it would only really be for myself and a few others who use alternate Android OS's.
