Agreed here.

I think that the absence of any portable way to implement correct
hash tables on inexact numbers is in fact a game-stopper.  It is
an indication that the standard is too flawed to release.

We already guarantee this, with the exception of nans which
are unspecified for R5RS and existing implementation compatibility.
No one else was complaining about nans, but is this what you're
worried about?
