Then this should be written to be less ambiguous.

Debian policy does not mandate that packages support TMPDIR,
so it is valid to package a program that does not support TMPDIR and
always use /tmp instead.

However if some other package use this program in its own build process,
then this other package is RC buggy under this new rule. This can be
inconvenient.

Do we have some data about how many packages fails to honor TMPDIR ?
