As far as I understand, the concerns were about comma expressions,
and that ship has sailed with the depreciation in 20.
I suppose C might want to talk about doing something similar there, as that
technically include an incompatibility.

To my knowledge, none of the authors has been reached about further C

And as you are pointing out, this proposal does not affect C arrays.
