I think it all depends on much effort we[*] are willing to make.

At this point in the life of bookworm (which is 2/3 of its supported
period), there are already at least 60 different ftbfs bugs, so I
would say that fixing the FTBFS problem alone (disabling the offending
tests, if that's your plan and you know how to do it) would be more
than acceptable and a lot better than nothing.

[*] I say "we" because I'm also a team member, but I certainly can't
fix all the issues and I definitely appreciate any kind of QA work
that others might offer (like fixing ftbfs bugs in bookworm).

Thanks.
