Not *easily* possible. Not impossible.

That's why the old option is still available "deprecated" for a while. But
no new functionality will be added. IOW it will remain compatible to how it
was when it was deprecated (2.6.0 compatible).

If you can't change it out of compatibility, this will be no problem, since
the current interface should be exactly compatible to 2.6.0 and before.

No it wouldn't, since  -xx="bla" needs to be dequoted on windows (and I
assume OS/2) too.

Your message is a very good example why the whole splitting and escaping
approach was abandonned.  Every issue was considered to be "just add this,
since then it works for me now", but after multiple years of such changes,
there are still corner cases left.
