Naturally. But I like to keep an eye on those things (maybe providing
feedback) before they become real warnings.

If the maintainer scripts become a tangled mess of if-then-else (read:
technical debt) the cost of maintaining those scripts soon becomes very
real quite fast.

As an unlucky person who just replaced an inherited 500+ line shell
script [doing things no longer needed for the last 10 years] with a 40
line perl version I can attest to that problem.

So I can see where this check is coming from.

I believe in some packages (not ours) one could even drop a maintainer
script all-together after removing cruft to support updates from Etch to
Wheezy.

So a little nudge from lintian to check of there are any cobwebs to
remove isn't a bad thing, IMHO.

Grüße,
Sven.
