Throw an error if not all patch keys are used

[tomerslice]

Hello,

I wanted to suggest a flag to check if all patch keys are used, and if some patch keys are missing data to replace with.

This validation will help to check we are not missing anything we want to replace or we are trying to replace something that is not exists.

What should happen? Log a warning? Or throw an exception?
