JSTEP-13: LTS versions for/or Jackson?

[Tatu Saloranta]

So, I was suggested something that seems like a good idea: consider
adding concept of Long-Term Support(ed versions/branches) similar to
JDKs.

I wrote bit more on

https://github.com/FasterXML/jackson-future-ideas/wiki/JSTEP-13

(TL;DNR; some but not all versions could be considered LTS, kept open
longer than intervening "short-term" minor versions; expands timespan
of supported (oldest) version, gives users more predictability)

but more importantly, opened a discussion here:

https://github.com/FasterXML/jackson-future-ideas/discussions/84

in case anyone wants to exchange ideas, comments, brainstorm.

All feedback appreciated,
