I agree we need some kind of LTS.
On the old ports system it didnt matter, but now if you have a EOL release then ports tree gets disabled so its effectively enforced. For server use when you managing many servers 2 years is a nightmare too low. If the dev's say tough luck you can manage, then thats the type of attitude that shrinks their userbase, the competition supports LTS.
Bear in mind tho the STABLE branch itself lasts longer than 2 years, the page is misleading as it doesnt publish the actual end date but instead the end date of the latest RELEASE in the STABLE branch.
I would like to see the return of the extended point releases, I dont know why they got removed other than maybe developers putting themselves ahead of their userbase.
This policy may well be what loses me as a very long time FreeBSD user, the main thing keeping me now is the ports flexibility and ZFS. But ZFS is now pretty stable in linux so currently its a tradeoff between long term support and ports flexibility.
