Do you mean that you thought that unstable would not have problems
with uninstallability/transitions?  It does (in fact, it's the main
place where it happens, and I think that experimental is rarely used
for that directly).

The website points to this, although not mentioning "transitions"
directly but describing the effects -- in the last paragraph of this

View the packages in the unstable distribution

This area contains the most recent packages in Debian. Once a package
has met our criterion for stability and quality of packaging, it will
be included in testing. unstable is also not supported by the security

Packages in unstable are the least tested and may contain problems
severe enough to affect the stability of your system. Only experienced
users should consider using this distribution.

See the unstable distribution pages for more information.

The last line points to https://www.debian.org/releases/sid/index.en.html :


The unstable distribution (sid)

The code name for Debian's development distribution is sid, aliased to
unstable. Most of the development work that is done in Debian, is
uploaded to this distribution. This distribution will never get
released; instead, packages from it will propagate into testing and
then into a real release.

Please note that security updates for unstable distribution are not
managed by the security team. Hence, unstable does not get security
updates in a timely manner. For more information please see the
Security Team's FAQ.

sid is subject to massive changes and in-place library updates. This
can result in a very unstable system which contains packages that
cannot be installed due to missing libraries, dependencies that cannot
be fulfilled etc. Use it at your own risk!
