Using the scheme upstream uses (a subpackage with all the loadable
modules) you won't pull in any unnecessary stuff.

Creating a lot of subpackages, figuring out the dependency list for each
of them, and then asking the user understand which of many subpackages
he really needs, something which changes when he edits the main packages
config file which changes the set of loaded modules.
I see two potential complaints, each representing one end of a spectrum:
1) The main package is broken, it pulls in stuff I don't want (your issue).
2) The main package is broken, every time I try running the package in a
different configuration I have to install some other subpackage, why
can't they all just be there so I don't have to figure it out? (btw,
figuring out which subpackage is needed means knowing enough to look for
errors in the daemon's error log when it doesn't start successfully,
that doesn't seem very friendly either).
