I agree, wording sounds a lot better, included in v2 together with PR number.

The https://gcc.gnu.org/onlinedocs/gfortran/Invoking-GNU-Fortran.html
does contain a working link to
https://gcc.gnu.org/onlinedocs/gfortran/Interoperability-Options.html
However the manpage has Interoperability section explicitly disabled
with "@c man end" ... "@c man begin ENVIRONMENT".
After digging into git log it seems that Interoperability section was
unintentionally added after this comment mark in
https://gcc.gnu.org/git/?p=gcc.git;a=commitdiff;h=e655a6cc43

Subject: Fortran: Add Developer Options mini-section to documentation
Separate out -fdump-* options to the new section. Sort by option name.
While there, document -save-temps intermediates.
gcc/fortran/ChangeLog:
PR fortran/81615
* invoke.texi: Add Developer Options section. Move '-fdump-*'
to it. Add small examples about changed '-save-temps' behavior.
