--- Comment #1 from anlauf at gcc dot gnu.org ---
I don't think the wording of g95 is explaining what is wrong.

Browsing F2018 I saw:

C15103 In the specification-expr that specifies a type parameter value of
the result of an elemental function, an object designator with a dummy
argument of the function as the base object shall appear only as the
subject of a specification inquiry (10.1.11), ...

And 10.1.11 has:

A specification inquiry is a reference to

(1) an intrinsic inquiry function other than PRESENT,
(2) a type parameter inquiry (9.4.5),
(3) ...

TRIM and LEN_TRIM are not intrinsic inquiry functions.
