Compatibility Tables

I was editing some pages (
http://docs.webplatform.org/wiki/dom/methods/hasAttribute, for example) and
I see that ALL CAPITAL LETTERS note that tells me not to edit the
compatibility table.

Am I actually disallowed to edit them?
If so, where should I edit this information (or make sure the automatically
imported information is correct)?

And the sneaky question - what happens if I do edit them? would it break
the automation? would my information be discarded once the automation
effort is complete?

Would I be committing a sin? would all hell break loose? would I go to
jail? I can really go on and on.
