a) You miss a check whether the finalization procedure is a subroutine. Currently also functions are accepted.
Should there be any? I thought it could be both (and for functions the return would just be ignored or something like that).

Fortran is not C and makes a real distinction between functions and subroutines. It is not possible to call a function without assigning/using the return value somehow. Additionally, 4.5.5. explicitly states:

"The FINAL keyword specifies a list of final subroutines."

Note the word "subroutines" -- and not "procedures" which denotes both subroutines and functions.
