(attempting to CC all potentially interested parties) I'll wait a bit longer but it looks like there are no developers interested in maintaining Ada. There are at least two users willing to help though. Since our wiki doesn't allow listing users as a project, and Ada doesn't maintain many packages, I suggest that we start by disbanding the project entirely and moving the packages to maintainer-needed. They could be afterwards grabbed via proxy-maint. Unless Ozgur (or someone else) shows interest in the two dev-ada/* packages, I think we should lastrite them and just leave gnat-gcc (the Ada compiler). As for gnat-gcc revdeps, there would be two left: a. net-mail/topal [net-mail], b. sci-electronics/ghdl [sci-ele]. AFAICS topal is already in process of being killed, so we will eventually lastrite it. GHDL is probably worth keeping, though I guess its maintenance could use another pair of hands.
dev-ada/* treecleaned, project disbanded, remaining packages are m-n now.
