Well, I think in many situations pack and prune can be controlled. To be 
precise, if alternates are used pack and prune *must* be controlled. 
Currently, the control is very simple: "don't prune" (and I don't recall ATM 
what you must not do when you repack).

Anyway, judging from the responses so far it seems that people can live 
with "don't prune" (or not using alternates) ;-) Repositories getting broken 
this way isn't exactly my itch, either, so... I spelled out a possible 
solution if someone wants to pick up the topic.
