Thanks Arjan. I did not actually oppose making it non-modular, and
thought there was sufficient time for people to complain meaningfully
on that change. I also think there's not a lot of value in the modular
interface, but it's very difficult to have rational discussions in this
area.

Yes, and I think we can still improve performance although I can't see
anyway to help out the modular case, so I guess it will have to incur
the hit that's always been there. I think your Kconfig option is a
decent compromise.
