I used KeePassXC as the Linux client for 1Password before there was one from AgileBits, and stopped short of implementing _write_ for the opvault format because that wasn't in my use case (and I also had some non-trivial concerns about KeePassXC accepting the PR, so I was trying to pitch it as a way to get more people to import 1Password opvaults)

I would be on-board with implementing the write side to opvault if they'd accept the PR, and would also implement the browser extension protocol server if 1Password would specify it, since as others have pointed out the KeePassXC browser extension is suboptimal

Then again, with all the massive outpouring of Bitwarden support in every single one of these threads ever, I am pretty sure the real solution is just to bite the bullet and jump ship to Bitwarden/vaultwarden like everyone else seems to be doing

I'm willing to stick around long enough to see if AgileBits makes good on their local vault something something, but given the past few years of activity, I'm going with "they're bluffing" or "it'll be a horribly hobbled implementation"
