Appending these notes at the end of all the tables does not strike me
as a big dea, TBH. But, well, my sole opinion is not the final choice
either. For now, I am mostly tempted to keep the generation script as
minimalistic as possible.

Documenting what's expected from the wait event classes is critical in
the .txt file as that's what developers are going to look at when
adding a new wait event. Adding them in the header is less appealing
to me considering that is it now generated, and the docs provide a lot
of explanation as well.
