the old archlinux kde3 project called kdemod3
actually did this. Everything was modularized so you only
had to install what you wanted. We are planning on doing
this with our Arch Linux packages now. Pawel is heading up
that front.
As an R15 priority I VERY MUCH would like to see a move toward modularizing TDE. That move
would reduce build and debugging issues and could very well induce people to download
specific TDE packages.
Please share this information with the dev team!
