As a preliminary step could we have a script to verify the function calls
in each addon are still valid on a daily basis.

Just iterate across every function definition and validate against the
latest repo to check if the variables/structure of the calls are correct?

If any breakages are found send en email to the addon maintainers so they
have a headsup on what they need to fix.
