Personally I think this would be a bit much to ask...it would be fairly
annoying to have to wrap all one's functions like this, even if there
was a macro to do it.

What about asking library users to say something like

(eval-when-compile (defvar org-element-custom-standard-properties ...))

and then using a with-standard-properties macro within
org-element-ast.el to make use of this value at compile time?

I don't know if that would work if e.g. org-element-ast gets compiled
before the user's code, but an interface like that seems preferable to
me.

Best,
