Commit de63ab6 "migrate: Share common MigrationParameters struct"
reused MigrationParameters for the arguments of
migrate-set-parameters, with the following rationale:
It is rather verbose, and slightly error-prone, to repeat
the same set of parameters for input (migrate-set-parameters)
as for output (query-migrate-parameters), where the only
difference is whether the members are optional. We can just
document that the optional members will always be present
on output, and then share a common struct between both
commands. The next patch can then reduce the amount of
code needed on input.
I need to unshare them to correct a design flaw in a stupid, but
minimally invasive way, in the next commit. We can restore the
sharing when we redo that patch in a less stupid way. Add a suitable
TODO comment.
Note that I revert only the sharing part of commit de63ab6, not the
part that made the members of query-migrate-parameters' result
optional. The schema (and thus introspection) remains inaccurate for
query-migrate-parameters. If we decide not to restore the sharing, we
should revert that part, too.
