Yup, something like:
or we could just assume this is the minimum and omit the >=

This is how it has been in the past, if __init__ .py doesn't have
name(), description(), and version(), it won't be loaded... Also, since
current plugins won't be able to work with the new API without
significant changes anyway, asking plugin developers to add a new method
to their __init__.py files won't really be asking that much more ;-)

I agree, max version will likely be unused/unnecessary...
