Comment 8 for bug 195397

Its tagged wishlist, so no its not likely. Changing it is actually a lot of effort:
 - theres a lot of docs that have to be changed
 - we need a migration path for people upgrading who aren't new users
 - we'll need to test the migration carefully

And there are remaining issues like where plugins go, which are not trivial and may even require changing the XDG specification to have a place for them.
