Forced mutation of user operations during Horreum to h5m conversion

[willr3]

The new import command for the legacy operations (Transformations, Labels, etc.) was updated to change recognized javascript operations to jq operations.
Who owns the operations? If the operations belong to the users then making this change without their consent is the same as a spreadsheet changing a formula because it produces the same output. h5m is performing a similar mutation converting Extractor jsonpath to jq but that is because h5m no longer supports the jsonpath based transformations. Extractors have to be converted to maintain functionality. Converting the javascript operations to jq is forcing users to learn the new syntax to improve h5m performance.

The migration from Horreum to h5m will likely be performed by system administrators without user input. Do we feel it best to automatically mutate user operations or provide users with a way to optimize the operations after they are migrated? Something like a pattern detection in the UI that suggests a "faster jq alternative" for existing js operations?
