Aren't we trying to move away from the 'usual'? Considering things on
a case by case basis still requires review cycles, etc. Keeping the
status quo would mean prolonging the exact pain we're trying to
address.

I was thinking of the bold move of having Kilo (and beyond)
developments solely focused on this transition. Until this is
complete, nothing would be merged that is not directly pertaining this
objective. At the same time, we'd still want pending features/fixes
(and possibly new features) to land somewhere stable-ish. I fear that
doing so in master, while stuff is churned up and moved out into
external repos, will makes this whole task harder than it already is.
Thanks,
