maintscript files are for debhelper (dh_installdeb), not dpkg.

I don't see much difference between 1 file with 10 lines and 10 files
with 1 line each.

The "package" argument is not about the package that makes the changes,
but about the package owning the stuff being acted upon. Usually both
are the same and the "package" argument can be omitted.
I think the "package" argument is not used for symlink_to_dir, but
needed for dir_to_symlink ("Is all the stuff found in dir owned by
$package?"). Or for rm_conffile/mv_conffile cases where the conffile was
previously owned by a *different* package.
Maybe something could be accomplished with dh-exec, but that sounds like
overkill ...

PS: at some point I would have liked to put all the lintian overrides in
one file ... it sounded so natural to just dump a bit of lintian's
output into a single ignore list ... and so redundant to prefix each
line in $package.lintian_overrides with "$package: " - but luckily that
can be omitted :-)
