It would still be good for:

- trying to isolate the source of the problem without replaying everything up to the point where the desync happened

- when you know what caused it and it's actually something fairly easy to avoid, and you'd rather just keep playing and try to fix it later

- when you know what actions trigger it and it's actually something fairly easy to avoid, but you have no idea what exactly in the code cause it, and you'd rather just keep playing than wait for however long it would take for the modder to figure out what to do with your bug report

No. Unless you find someone willing to invest a lot of time here.

Would this be obsoleted by a shift to full client/server multi? I realize that's a ton more work and that branch hasn't seen much action lately...

Yes, because that would be essentially what it does on player connect, anyway.
