I have integrated this now, had first tried to put it in the middle but
then decided to add it to the end as you suggested (but without the "to
cover"), feel free to improve it yourself

yes, I agree this could be made more verbose. I agree with your
interpretation that it doesn't seem to prevent people from importing this
data now, but it clearly puts more obligations on us that will make future
license changes harder to perform. Feel free to add some explanatory lines

can you (or someone else) add these? I am not familiar with them and could
only replicate what you have written above.
