dpkg-dev does no environment cleansing, that's sbuild. I think what
you want is to modify its $environment_filter variable in .sbuildrc.
So, while the whitelist is indeed intended to list this kind of
variables that might end up affecting the resulting artifacts, I'm
not comfortable adding support for these, as it feels it would
legitimate them, when these tools seem to me to be clever hacks that
would ideally need to be properly integrated in the correct layers.
So given all the above, I'm inclined towards closing this report.
Thanks,
