It doesn’t have to go away per se, but we need proper ways to deal with
incompatible changes in the interfaces.

Of course, Python developers don’t have the monopoly on misunderstanding
maintainability requirements. It evens happens more often in C, where
the ABI can change without any incompatibility in the API. When this
happens without a soname change, we either change the soname ourselves
(diverging from upstream) or change the package name, making it
impossible to install two conflicting versions at once.
In Python libraries, this is not possible without changing the code,
since the file name and the module name are the same. If a Python module
changes its API incompatibly, we are forced to update all reverse
dependencies and add versioned conflicts, without being able to ensure
none is forgotten, and without enforcing the change for third-party

It will suffice, but we will not be able to manage it in distributions
if you allow too many weird things to be specified in these
: :' : We are debian.org. Lower your prices, surrender your code.
