How 'bout simply adding \\` and \\' around the string (without quoting it)?
All the entries I've seen so far are equal to their
regexp-quoted version, anyway.

Please use only ";;", since the first line above ends up using the
format of major outline header.

Why?

Yes.

So you don't need to distinguish those that start with \\ and those
that don't.  And so you don't need to modify every entry adding \\` and \\'.

(I am dumb and do not understand.)
But what if I want a regexp entry that isn't anchored at both ends?

While this is highly unlikely, it's very easy to get anyway, by adding .*
