I would say it is not worse than just "annoying"; if the cost will
go away, I'd rather see this conversion postponed and is done as
part of (and preferrably at the end of) the "poison with a
poison-locale" series.

Yeah, I think that is the right direction to go; I suspect that
"poison with a poison-locale" would have to be ready to allow us to
go there, though.
