I agree wholeheartedly.  My filters always have 3-input mixers on every
channel, and I use them a lot.  For CV inputs, I think you really need to
figure out how you use your modules, and customize them accordingly.  I
would personally never require 5 CV inputs for VCO pitch, as Harry suggests,
but peoples' needs differ.  If you overdo it, then you end up taking a lot
of panel real estate for stuff you will never use.  If you underdo it, then
you will always kick yourself every time you patch that module.  The nice
thing about DIY is that you can try stuff out, and if you want to make
changes, just make them, or do it differently on the next build.
