I posted the original post regarding 'p' records on the Postfix forum,
and these are two of the responses that I received.

He is referring to his mis-use of the non-public, undocumented Postfix
queue file format and plans to keep track of changes in this format
rather than abandon its use.

Mailscanner attempts to implement a fast-path for messages that are not
modified by the content scanner. It cuts too many corners to achieve
this goal.

It means that some people don't understand ELEMENTARY SOFTWARE
ENGINEERING practice.

I spend huge efforts to maintain compatibility with software that
depends on EXTERNAL Postfix interfaces, even when MAJOR changes
are made to Postfix. If something breaks anyway, then I will do my
best to provide a solution to make it work again.

Postfix queue files are an INTERNAL interface.

Software that depends on Postfix INTERNAL interfaces breaks the
warranty. It is unsupported. It breaks even with MINOR Postfix
changes, and I will not provide a solution when it breaks.

After a time, you may find that "having" is not so pleasing a thing,
after all, as "wanting."  It is not logical, but it is often true.
