Could you re-do the commits so that one commit is the refactor with the other commit having the fix? And describe the problem and the fix in the PR?

This is putting the burden on the reviewer to figure out what is happening with this and the team is already strapped for availability.

When adding a dependency, please expand on why it is helpful and why it is worth taking on.

In particular, this is adding a dependency in place of hand-implementing one Hash and one PartialEq. That seems like a fairly small scope that I would expect the dependency to be pulling a lot of weight.

Please expand.

Communication is critical in open source, especially when maintains have limited availability. So far the communication has been pretty minimal between this comment, this PR, and #11120.

I can make my own guesses and some of them might be quite valid but that is a one sided conversation with myself. I'm wanting to understand your intentions and reasoning.

Ping @Hezuikn. Just checking in to see if you are still interested in working on this. As epage said, a good conversation often leads to a better context of understanding to the solution. If you need helps, comment here and we could take a look.
