Hey, you are actually the first to give an argument for
saying that 6 (or 4) is too short... :)
I have already layed out the options for this in another thread
but noone has commented.
With our current approach of 3 supported releases,
(current, maintenance, security), we have this:
9 months cycle => 27 months lifetime
6 months cycle => 18 months lifetime
4 months cycle => 12 months lifetime
Of course on could consider adding two cycles of
security releases for a release (which arguably
poses the least efforts), then we'd have:
6 months cycle => 24 months lifetime
4 months cycle => 16 months lifetime
Not sure whethe that would be worth it but it might
be the easiest way to extend the lifetime.

I think that the distributors do already have to do
the work of maintaining backports to unsupported versions.
This is nothing new. And I think it would not change much
to move to shorter cycles. But maybe I am off here.
Maybe the maintainers of the distributors should comment
And with each single release being not such a bing change,
we might lower the bar for adopting newer versions,
possibliy in alternate software channel.

Right. This was the main point in bringing up the topic
of release cycles. (Which is actually a different thread.)
I have long advertiesed that we should not have any blocker
bugs at all, essentially.
The proposal is to stick with strict release schedule.
No excuses (technically). And the argument is that this
will be much much easier with shorter release cycles,
since slipping a release with a pretended blocker bug
just means a delay of 4 (or maybe 6) months instead of
12+ months which hurts much more.
And each single release should require less work and,
more importantly, less frustration.
