I have no problem with the history remaining in a retired Mercurial 
forest only. The advantage of retaining all history would be the ability 
to bisect, but this seems very rarely/never needed in 8u backports repo.

Others who do more frequent backports than me (Aleksey maybe?) might 
have more insights.?
