Is there ever any reason to not immediately convert WONAFYT?

Cause I'm pretty sure there isn't. Hell, even the nerfed APHEELSIK (which is also currently conversion fodder as far as I'm concerned) is good by comparison.
I keep expecting some kind of buff to this spell with each update, but it never comes. Is there really nothing planned for it?
