Do you think we could generalise this more? Say e.g. someone changes the post format to "link", but then immediate changes it back to "standard", I think we should avoid to create an undo level as well. Similarly we could have input fields outside block scope, which would still add records for each character change?

areValuesEquivalent sounds like an expensive calculation to execute on every action (an thus keystroke).

The undo state shouldn’t be related to components at all and maybe have something like this:
Compare the redux dispatch action triggering a change with the previous dispatched action. If the two actions are similar: which could mean, they’re both
UPDATE_ATTRIBUTESof the same block and they both update the same attribute and the only difference between these two attributes is a single alphanumeric character (not space etc...), override the previous undo state.If the actions are different, create a new undo state.
This would be very generic
