That's because I re-isntalled a fresh-baked qgis_unstable and the
default setting was(_is_) to load+render newly added layer(s). Could
this be switched off automatically if, let's say, a project has >30 maps
to load (or some threshold)?

OK, some projects:

* work(=open) properly
* just take TOO much time (...I suppose they will be loaded at some
point)
* don't appear with the groups I have build
