Not as bad as I thought. libSDL's dependencies in the util libraries
aree unused: checking for "dpkg-shlibdeps: warning: package could avoid
a useless dependency if FOO was not linked against BAR (it uses none of the
library's symbols)" (see below).

I'll try to do something, but if someone beats me to it, it would be
nice.
