After reading through everyone's responses I think it would make sense to
change my release lifecycle proposal from "24 months or whenever we have two
newer active branches, whichever comes first" to "18 months or whenever version
X.Y+4 is released, whichever comes *second*". Specifically, the new lifecycle
rules would be:
* At least two (and preferably exactly two) branches will be supported at any
given time.
* Starting with 3.0, each release will be supported for a minimum of 18 months.
After 18 months, support ends if this is the "Old Old Stable" branch.
* Releases preceding a major change will be supported for a longer period of
time, e.g. 30 months.
As shown in the diagram, below, 3.0 will have guaranteed support for 18 months
and support will end when 3.4 is released. Similarly, support for 3.2 will end
when 3.4 is released.

Most people preferred sticking with the current odd = development, even =
stable release versioning. I'm OK with that.
