What I suggested is that
1. The combination of legacy mapping macros and
legacy code using those macros causes lots of
PAGE0 warning.
2. Getting rid of the warnings requires a mass update.
3. A mass update is disruptive.
4. There is no easy fix.

Subject: Re: Getting to CVT with FLAG(PAGE0)
What are you suggesting as a "fix"?
If a symbol such as CVTPTR has been defined with an EQU (as it
has since OS/360 in the 1960s) it obviously cannot be redefined
to make it relocatable (for example as a field in a DSECT)
without triggering compatibility problems in existing code.
