Note that this decision has been taken because: - dpkg-source has never used debian/substvars as input and did nothing unless you gave the -T option, however the source package can't pass additional option to the dpkg-source call made by dpkg-buildpackage (so it never worked as Charles expected it to work, and furthermore the dpkg-source call happens very early in the build process which means the substvars content for this call would have to be fixed or generated in the clean rule) - dpgk-genchanges has very few content that is copied straight from debian/control and the substvars support only ever allowed to change some fields like the Format version (which doesn't make any sense) On Sat, 31 Jan 2009, Charles Plessy wrote: > I am not sure I understand.

I hope my answer clarifies the situation. Given that it has not been used in 14 years, and that we had no wishlist bug in that direction, it seems pretty clear that it's useless and that there are other better ways to achieve similar functionnality.
