No way. Internalising the application navigation context model is onerous enough (where am I, which UI controls will get me far enough back to where I was); determining that actioning an http link is a further subsidiary context within that is nightmarish.

how about this bsky.app/profile/mozz...

Ingenious compromise, but even if so the default option should still be to open in the browser proper. Facebook & co have a vested interest in keeping The Internet as an obscured and limited subsidiary component to their totalising application experience.

facebook would prefer you to open a new tab in the default browser, since the in-app browser keeps a separate set of cookies and thus makes tracking harder

Not true. Facebook has actually disabled opening links in the default browser (on Android anyway), so everything stays in-app. You have to download an old APK to find the option, turn it on, and then update your Facebook app to the current version to be able to do that.
