The exact wording that was added, was a too-loose requirement. I'm now proposing to make the requirement more strict, in accordance with the tests that we're running. Do you have any comments on my proposal?

- a set of environment variable values; and
+ a set of reserved environment variable values; and

then later:

+ A "reserved" environment variable is defined as DEB_*, DPKG_, SOURCE_DATE_EPOCH, BUILD_PATH_PREFIX_MAP, variables listed by dpkg-buildflags and other variables explicitly used by buildsystems to affect build output, excluding any variables used by non-build programs to affect their behaviour. Explicitly, this excludes TERM, HOME, LOGNAME, USER, PATH and likely any variables ending with *PATH.
