I think that, in general, we should avoid
"I think this is broken, I don't care to fix it, and so I am going to
delete it".
This is an invitation to allow someone to delete capabilities simply because
he/she is too ignorant and/or lazy to understand something,
but is merely energetic enough to delete a file or edit out a name.
In reality we have no mechanism for voting on keep/delete/rename/ except
a pseudo consensus --- no one has recently objected to doing this so it
must be OK. Or even somewhat less than consensus, e.g. I, the author,
want to include xyz and no one has vigorously objected, so it goes in.
