Question: Can't we add an option that does exactly that? Anything that'd 
prevent us to do so? 

Proposal: Build everything that is a dependency of the package passed to 
kdesrc-build. I personally would like to have this as well.

A first time user ("I want to hack on plasmate") could then just invoke 
something along:
$ kdesrc-build --include-deps plasmate

Hm, but in fact it gives you the information about the actual package 
dependencies pretty precisely, no? (Otherwise the whole CI infrastructure 
wouldn't work -- Our CI scripts can figure out the exact dependency set needed 
for a build)
