Sigh; true - it'll mostly speedup build time then; then again we could
filter them during / after generation I suppose.

Right; that is done already as we merge to a library.

Why do you think that Deps are 10% of the working directory ?
$ du -m workdir/unxlngi6.pro | tail -n 1
2906 unxlngi6.pro
$ du -m workdir/unxlngi6.pro/Dep | tail -n 1
1546 unxlngi6.pro/Dep

1.5Gb of 'stuff' in there I think - at least someone I sanity checked
