Hmmm, the problem is more complex than I've thought in the first place
because the code to clean up the menu of junior-* packages is contained
in blends-common.  So it is not enough to verify whether the code exists
and just exit in case the test fails.  I have to find a way which
ensures that blends-common is removed *after* removal of all junior-*
metapackages.

Is this a case for using Pre-Depends or is there any other way to make
sure  that blends-common will removed not too early?

Kind regards
