I agree this is a good/safe fix. Nice job on quickly handling simple problem.

We can do better in terms of r-explain. When I first read, "NFC Fix function name typo", that struck me as a non-sequitur -- renaming a function is a prima facie change in a contract, which is prima facie functional, therefore not NFC. As someone skimming the changelog, the message just confuses me.

Suggested commit-message/PR title:

CRM_Utils_Rule - Fix typo. Rename checkExtesnionKeyIsValid to checkExtensionKeyIsValid.

or maybe:

CRM_Utils_Rule - Fix typo in checkExtesnionKeyIsValid
