Part of it could be inertia - we've not done it before, why start now.

But there is also the problem of installing pcp into chroot
environment - you really don't want to be starting it there and it's
most likely isn't going to run.

If pcp were ever to be split into pcp proper, pcp-devel, pcp-eoe etc
then the issue of installing the whole caboodle into chroot for builds
is going to go away.
