Comment (by bgamari):

 > Is there anything blocking this ticket or does someone just need to
 implement it?

 There's nothing particularly blocking. The plan that I wrote about may or
 may not be the right way to go about this. It's also quite unclear what
 the right way forward would be if it turned out that implementation hashes
 are expensive to compute.

 Regardless, osa1 may be looking into this for Well-Typed client at some
 point in the next few months.
