Though being not even a committer, I have some opinion about this topic: I’d clearly vote for option A at this point in time.
There are many good arguments for option B. Some of them are outside of Maven, e.g., IDE support. But I see that even JetBrains people never complained (and I opened some bugs on Maven 4 support in the last 6 months, cf. Slack thread). Internally, it doesn’t make such a big difference due to usage of Modello etc. However, option B could perhaps simplify Maven (core) in the long run: I did a quick analysis with the help of some LLM which shows that option B enables to follow certain software engineering principles like SOLID. But I would have to verify this, for which I do not yet have the time. The practical impact should not affect us too much under the assumption that a future version 5.x would introduce heavier changes (and we could reconsider namespacing then again). Having said that, my vote goes towards option A as it is already there for four years, obviously not causing too much harm. Sometimes one needs to meet a decision and this time seems to be now (at least for this concern). Have nice easter holidays everyone! > On 1.
