Right, I see what you mean.

OTOH, the same could be said for several of the fields in the .dsc, such
as Build-Depends, but we still list them because it's more convenient to
not have to extract the source beforehand.

TBH, I hesitated a bit before adding this, because this percolates
into many other places. But considered that, while the information
could be retrieved in other ways, it made life easier for test
runners. And we can always remove it if it ends up being

But I certainly agree that this should have probably been discussed
more widely, which is something I overlooked, sorry about that. And
agree completely with your two points above. So I'll be adding an
entry to the FAQ detailing the process to add new information to
the .dsc file (and probably to the .changes and other interchange
