What I mean is, that if a *user* would keep an older version of gsasl 
and would install the new dovecot, would they see (some) broken behavior 
or not? And in the reverse, if they would keep the old dovecot, but 
upgraded gsasl, would that work for them? In either case it needs a 
versioned relation. If the failure is only in the test (which I think 
I'm reading in your explanation above), one of the two relations will 
help the migration software to figure out what tests to run, but for 
test only failures some maintainers feel like that's overkill. You can 
add the versioned relation also to the *test* dependencies, but the 
migration software doesn't inspect that itself. For the cases where 
maintainers prefer not to add the relations for test only failures, I 
can schedule the combination manually.

Hope this helps too.
