2.18.2 requires (define-music-function (parser location spec) ...

The first version to allow (define-music-function (spec) ... is 2.19.22
and the first version to allow (thumbBracketEx spec settings) is 2.19.22
as well.  So if you drop the "parser location" arguments, there is no
point in not calling thumbBracketEx directly.

Of course, the `let' is spurious.  You can just use thumbBracketSettings
directly instead of settings.  Probably as of 2.14 or something.  So
either way there are some more possible streamlinings even when writing
for 2.18.
