@jakehamilton Compared to other features, I regard flakes as a well-undercooked feature deserving of its experimental status (seeing as it was jammed in there and that's the only flag we have to deal with the mess).
As such, I would percieve a repository with the feature issues un-addressed, yet marking the feature as mainline, as a technically less solid offering.
Many software solutions strike the middleground of offering to enable experimentals at install time.
