If packages had a way to opt-out of needing the whole standard library, and instead specify the stdlib subset they need, answering questions like "will this run on my phone?" and "what piece of the stdlib do we want to port next?" would be easier.
On the flip side, answering questions like "what version of Python do people need to run my program" become harder to answer, particularly if you have third-party dependencies. (The latest version of numpy might decide that it's going to 'import statistics', for instance.) One of the arguments against splitting the stdlib was that corporate approval for software is often hard to obtain, and it's much easier to say "I need approval to use Python, exactly as distributed by python.org" than "I need approval to use Python-core plus these five Python-stdlib sections".
