I don't think it belongs to "org-entities.el" either. While it is true
there is some prettification done there, this is not the sole point of
the library. IOW, it is more than eye-candy; it affects, e.g., export.

I really think it should go into a new "org-art.el" file.

More comments follow.

Should this be a defcustom?

Also, note that the name space must match library, so if it goes into
"org-art.el", it ought to be named, e.g., `org-art-prettify-alist'.

"Non-nil if symbol between START and END should be prettified.
MATCH is ..."

Doesn't this mean that any bold object in headline is going to be
prettified?

Maybe something like this (untested):

  (and (org-match-line org-outline-regexp-bol)
       (< end (match-end 0)))

> +    ;; else rely on the default function

Nitpick:

  ";; Else rely on the default function."
  
> +  ;; Setup prettify mode

Ditto:

  ";; Setup prettify mode."

> +  (setq-local prettify-symbols-alist org-prettify-alist)
> +  (setq-local prettify-symbols-compose-predicate
> #'org-pretty-compose-p)

This should also go into "org-art.el", which is an optional library. We
don't want to activate anything related to it every time Org is loaded.

Can it be tested somehow?
