Then I'll reply here as well (content is the same as -devel):
Current practice is to use Build-Depends to specify build dependencies
in a way that the buildd network will successfully build packages. The
data might also be of (limited) use for other purposes.
We do *not* specify additional Build-Conflicts (that might make builds
fail / produce different results). Neither does the buildd network
require that packages already installed are listed additionally in
Build-Depends to install those and build packages successfully.
The set of preinstalled packages in build environments is decided by
the debootstrap implementation, so yes, the debootstrap behavior is
current practice.
If you want Build-{Depends,Conflicts} to provide stronger promises,
that is a change from current practice. And could be extended to
forcing /usr/local to be empty and a sane, standard environment and
contents of $HOME and anything else that could affect build results.

(I replied in -devel but should have replied here). What you call current practice is only current debootstrap behaviour. There are already packages in bullseye having build-depends on tzdata, and afaik it was not me who reported them to have such build-dependency. If current practice was really not to consider tzdata as build-essential, as you say, somebody would have reported those build-dependencies as a bug, because we don't use build-depends when the package is build-essential. I would say, therefore, that current practice all this time has really been to report those bugs and fix them, i.e. current practice is that tzdata is not build-essential, despite debootstrap behaviour. Thanks.
