Python 3.5 entered security fix only mode. Should we now remove the
"needs backport to 3.5" label? Other security only branches don't have
this label neither (3.3 and 3.4).
Seems reasonable to me since you will need to get Larry's attention and approval anyway for 3.5 changes now so the label isn't that useful. If there isn't a consensus to not do this I will remove the label probably Friday.
