This is the whole point of compat levels.
Unfortunately there is a lack of recognition how many bugs are
introduced by blindly updating debhelper compat levels - staying
at a deprecated compat level is better than a not properly tested
compat bump.
To be fair: You can assert statically if the compat bump did not
introduce any changes (by compiling twice).
