We have three (four if you include PatternFly) ongoing threads about
dependency
issues at the moment, and I hope we all realize that Alon is trying to do
what's best for our project. I certainly empathize with him. He has a tough
role, and there are a lot of us young'uns who want 'shiny new things'
brought
into the project. I certainly don't have the experience to know about all the
long term costs of bringing in dependencies into an enterprise project like
this
-- but I'm learning :)
I don't think that motivation to introduce new dependencies is driven by
desire to have "shiny new things" (we're not kids, right?) - I think that
motivation is driven by actual needs, backed by potential value that might
be broght in. For example, better/easier code due to newer version of library.
I agree that we should avoid maintaining packages ourselves as much as we can,
I think that everyone's in agreement with Alon on that.

I think collections4 is a nonstarter because it's not packaged for EL, IIUC.
