I'm not sure that to many document commands should end up here, but I
guess you have a point. (An aside: a macro used to store tokens is a
variable, not a document command, but as yet we have no document-level
LaTeX3 command for these cases.)

Basically, this all comes down to having expandable variants of document
commands, and deciding how best to specify these.
