In the working group you weren't listening and being rather combative and
demanding that I do stuff, so I stopped talking. It should not be taken as
a sign of my consent, but more a sign of not wanting to get into a yelling
match in public on a topic I thought had been settled months ago.

That's way too long. 12 will have Lua by default, but you can build FORTH
if you want has been the plan since February when I socialized this on arch=
@.
I originally pitched coexistence, but there was little appetite for that.

So I think a FCP discussed in arch@ is the right path forward.
