EVMS has this already.

It works and is supported (whereas I didn't think raidreconf was).
It would be nice to move the EVMS raid5 extension code into the core md.

FYI, I used EVMS briefly and found it to be an excellent toolset. It's a 
teeny bit rough and a bit OTT for a personal server though so I'm 
sticking with md/lvm2 for now :)
