That's what it seems, yes.

If you want to be sure, you could in theory start from a minimal chroot,
then try adding the packages that you have in your unstable system,
one by one, until the end result becomes different.

In fact, you have discovered a potential Build-Conflicts, but the number
of potential build-conflicts is so big that many people would
not consider worthy to know which one it is (unless you are curious).

In practice, we just take for granted that the build should
be done in a minimal chroot.

Thanks.
