:-) I was afraid that we'd find some of other sections that
needed to be excluded... :-/

OK, at least for now, but just a nit:

The comment should say "a few sections" as opposed to "a couple" (a
couple is two, or three at most), and it should say that there is no
other way to identify these section except by name.

Pre-approved with that comment update.
