Thanks for putting together this PIP to continue this discussion, Matteo. This is an important one.
I'll need time to think over your points before I respond, but I want to address two of them right away. > Actually, I was wrong.

We actually do have this documented on the website. I added this page in February: https://pulsar.apache.org/docs/next/security-policy-and-supported-versions#supported-versions. > we'd be releasing 2 LTSs super close between each other > and we'd have to support 1 release more for the time being. I agree with this reasoning. If 2.10 is LTS, and I think it should be, 2.11 shouldn't be LTS.
