MutationCache undocumented methods

[Birkbjo]

Hi!

I've a simple question: there's multiple methods on mutationCache that are not documented here, eg. remove(), find(), findAll(). Are these safe to use, or are they not considered part of the public API?

I wouldn't rely on it. For example, find is totally unused in our code-base, so I might remove it as it's undocumented. Generally, we try to respect public methods though.

So is there another way to do something like this: #4131 (deduplicate identical mutations).
How would I remove a particular mutation while I'm offline? Is there another way to do it, or is the consensus to just send all mutations to the server to more accurately simulate online behaviour?
