The above two would be much better beginning of the log message for
this change modulo a few nits.
- We first explain what the current system does in the present
tense. "Currently, " at the beginning is a pure noise.
- And we point out what may be lacking (which you did a very good
job in the second paragraph).
- And finally, we write in imperative mood to give an order to the
codebase to "become like so." or an order to the patch monkey to
"make the codebase like so."
As the last paragraph to follow the two paragraphs, something like
Allow the selectors to begin with these special characters.
would be sufficient.

As we seem to allow ? (i.e. zero or one) in the patterns, it probably
makes it easier to read to spell the above like this instead?
- "^[_a-z0-9].*$",
+ "^[:[@.#]?[_a-z0-9].*$"
