So they should tie the development to an extension that isn't in further development?
A better solution for a case like this would be to import the function from the Python standard library into the Flask namespace, so old code would still work. Then it wouldn't matter that Flask-Login is no longer actively maintained.
Also, as the article notes, Flask-Login is by no means the only Flask-using Python package that was broken by this change. Are all of those other packages no longer actively maintained? I doubt it.
Package maintenance also means to keep up with changes in the packages dependencies. If I don't do that, that's my problem, not the dependencies.
If I want to fix a certain version as my requirement, I can do so. Every major package system, including the ones used in Python, allow this. If I don't want that, then I need to keep my package maintained, and that means keeping an eye on what my dependencies do. That's part of package maintenance, simple as that.
There is no onus on the dependencies maintainers to care about whether I do my maintenance or not.
There's no "onus" on Flask to do anything they don't want to do. But if Flask forces every package that depends on them to fix a breaking change that they could have avoided with a one-line import statement, I would argue that is not very respectful of all those other package maintainers.
Forever?
- It's a significant piece of functionality.
- The change is trivial, not worth the cost of losing login.
In some instances Python deprecates something for six years, Flask six months.
