well I don't :-)

I think it should be \cs_use:c that should vanish.

look at it from the perspective of the corresponding base function:

   \use:n

you can argue that this is a short form for \use_arg_i:n (because it is so
common "bla bla"


   \cs_use:n

but what is the semantic of this supposed to be? what does it has to do with
"cs" as a module?

I could accept that \cs_use:n  =3D=3D \use:c  if anybody wants to make a ca=
se for
it (ie \cs_use:n is a function that takes an argument turns it into a csname
and executes it) but I don't really see a need for that ... anyway, this is=
n't
what the base function would do right now.

so my vote is

 \use:c

or replace it everywhere with

 \use_arg_i:c

cheers
