I agree.

That's why I think we should NOT have packagroups inside the BSP
metalayer, but in a different layer instead.

In a different layer we can have as much as possible/whishable, with
as much as possible purposes, colors, sizes.

Well, at least for graphics. I'm still trying to convince myself for
the other possible BSP packagegroups, but It's very hard to get an
argument for it.
