There are lots of mechanisms:

 - Andrew picks such changes up

 - With a few competent eyeballs on it (reviewers) this can go thorugh
   the trivial tree as well. It's more than obvious after all.

 - Send the script to Linus with a proper change log attached and ask
   him to run it.

 - In the worst case if nobody feels responsible, I'll take care.

All of the above is better than trying to get the attention of a
gazillion of maintainters.
