Current situation is quite different from what we had earlier. In the
old model, each new version was really new, forked fresh from Factory,
so that there was in actually no real "major" and "minor" version. As
new versions came each 6 or 8 months (more or less), noone could blame
users who did not want to do a full upgrade to new codebase so often.
That's why there was an overlap between [n] and [n+2], so that you could
skip e.g. 12.2 and upgrade directly from 12.1 to 12.3 without losing
support at any moment.
With Leap 42.x, core packages (mostly) follow SLE ones where the policy
is that upgrading in a new service pack should be well reasoned, not
just "hey, there is a new upstream version". And this logic should apply
to most of the distribution - or at least that is the plan. There are
exceptions, of course, as some packages do not fit into this model well
and some maintainers do not agree with this policy, but in general, Leap
42.x and 42.(x+1) should be much closer to each other than e.g. 12.1 and
12.2. Therefore users should fear upgrading to next point release less
and it should make much less sense to skip 42.2 and upgrade 42.1 systems
directly to 42.3.
What is a different story, though, is moving to new major version with
completely new codebase. IMHO we should think very carefully about the
overlap of lifetimes of last 42.x and 43.0/15.0/whatever it is called.
IMHO it would make good sense to have longer overlap (12 months?)
