May-be, one consequence however is perl and python now being glued together.

Sure, we can't avoid RH's addiction to python, but that's not my point. It's the impact glueing perl and python together has on upgrades, such as user-upgrade from Fedora N -> Fedora N+1, or python/perl version jumps. This impact already is visible when upgrading Fedora 13 to Fedora 14. That's why I am asking * Why does perl need systemtap? * What does perl use systemtap for? So far, I haven't seen any answer to these questions. When regarding this from one angle, this is simpla a matter of lack of communication, however when regarding this from a different angle, this leaves room for speculations along the lines of how "@RHs treat the community" rsp. about RH's governance in Fedora. Provided the language certain @RH's used in bugzilla, I for one have little doubts about what is going on.
