Apply operation history from json file not working

The ability to extract and reapply an Undo History was a quick hack that was thrown together to allow a set of operations to be reapplied to the same file or a file of identical shape. Once you deviate from this, you are in uncharted, and more importantly, untested territory. Unfortunately, missing, along with all the other error checking, are any checks to make sure that these constraints are being followed. The constraints exist only as verbal warnings passed down through the community.

I understand this. I also (and I think I was clear about this in my reply) understand why the changes were introduced and I’m not asking for this checking to be removed.

However given this is how OpenRefine has operated for as long as I’ve used it, and I’ve found it occasionally useful (as others have clearly based on this thread), I think it’s reasonable to ask for someway to recreate the previous behaviour - whether that’s by an ‘override’ for particular errors in the Apply history, or by some other mechanism.
