As (Steve Hay)++ said on-list:
I think it's a shame if users get a 5.X.0 release with some shiny new
features which I hope they're excited about and start making use of,
but then find bugs in those features and have to wait until 5.X+2.0,
rather than 5.X.1, for fixes.
rjbs++ clarified that, although such changes constitute a break in backwards
compatibility, there are two reasons why bugs in new features should be
fixed in maint:
* they delay people from using a feature for a year, because it does
something stupid
* they risk enshrining bad behavior under the usual program of bugward
compatibility

+stable release.
