Yeah I've been an advocate for better bridging, this seems to have been a hot topic back in 2023 but both sides of the Bridge seem pretty "luke-warm" about it these days.
Nonetheless I managed to browbeat Alex Gleason (he runs Mostr) into getting it fixed recently, so there's that :)
I know there have been some objections to the npub long usernames, but the bridges still generally present your NIP-5 username (i.e. "Globe99") as the primary user handle, with the npub as the "address".
Honestly I don't think this is the biggest problem... People on both sides are upset at the political / cultural attitudes on the other side.
