Hello,
I'm the new bird2 maintainer and I'm happy to help with this.

This results in
Version 2.0.12-7 of bird2 is marked for autoremoval from testing on Sat 19 Aug
2023.
I think this help noone.
If any of the two packages should be dropped from testing, it's bird as it's
nearing upstream EOL at the end of 2023.

bullseye contains bird_1.6.8-2.1 which is the same as bookworm,
so I tested on bookworm as it should be equivalent.

I'm unable to reproduce the error on purge after upgrade on my machine, in VM,
or in a container:
$ apt install bird
Setting up bird (1.6.8-2.1+b1) ...
$ apt install bird2
Removing bird (1.6.8-2.1+b1) ...
Setting up bird2 (2.0.12-7) ...
$ apt purge bird

On further investigation, the collision you describe is fixed by a patch
included in bird_1.6.7-1 (2019):
https://salsa.debian.org/debian/bird/-/commit/7738791be2
It checks for the ownership of /etc/bird/bird.conf using ucf and only performs
actual purging (including the removal of bird user) when it should.
> disabling and masking the systemd units bird2 uses
I don't see such thing happening in current bird/bird2 package sources:
https://salsa.debian.org/debian/bird/-/blob/master/debian/bird.postrm
The problems you describe imply upgrading from older bird package than 1.6.7,
for example buster 1.6.6-1 but that that's old-old-stable now.
This seems fixed both in bookworm and bullseye. IOW upgrading from a fully
upgraded bullseye system bird_1.6.8 to bookworm bird2_2.0.12 seems to work.
Are you sure you upgraded from latest bullseye bird package?
If so, I'm afraid you might be a victim of a fallout from previous package
versions.

They cooperated just fine in my testing with current bullseye/bookworm
versions and the above-described patch seems to have addressed exactly this
issue.
Please provide a reproducer with current (bookworm/bullseye) packages,
otherwise I think this was fixed in bird_1.6.7-1.
