My comments were not restricted to PL/I, but apply generally to
any compiler, and specifically Ada was intended. Since I had put

I also played with generating precisely the sort of warnings that you
refer to, but found it generated too much "clutter" of questionable
value. That was my view, FWIW

I think you are right about clutter in programs that contain a lot
of global variables. For example, in a COBOL program, where
the data is organized (pre-OOCOBOL) in a DATA DIVISION,
these kinds of warnings would be clutter.

In other languages with global variables the same would be true.
I recall early Ada programs where the designers would create

package COMMON is -- Fortran programmers
package DATA_DIVISION is -- COBOL Programmers
package COMPOOL is -- CMS-2 and Jovial programmers
