Yes!  It might be as simple as:

   for x in /usr/lib/snapshot/writers.d/*
     test -x "$x" || continue
     "$x" quiesce

... in the pre-freeze script, and the same loop with "resume" as an 
argument in the post-thaw script.  I'd also like to see services that 
need to quiesce their data ship with a script to handle that.
