Yes.

My thinking is that we've been disallowing template parameters of 
floating-point type for a while now.  If we really want to allow 
constant expressions of floating-point type forever more, we ought to 
also allow template parameters of floating-point type as well.

Furthemore, deprecating the extension doesn't make it impossible for us 
to keep it -- but it does make it easier to remove it.
