See: http://qa.debian.org/popcon.php?package=cyrus-sasl2

Summary:
libsasl2-2 install base: 98.94%
libsasl2-modules install base: 54.72%
libsasl2-modules-sql install base: 1.17%

Personally speaking (I'm not a package maintainer), I think these 
dependencies should belong in the packages that use them (such as 
cyrus-imapd). libsasl2-2 itself should keep it's dependencies small.

The gssapi and sql packages have a fair amount of 3rd party dependencies 
that many admins probably won't ever need.
