FWIW, the whole notion of having a LTS release seems primarily being pushed/supported and worked on by a single core developer, and it seems rather unlikely that a single contributor can maintain a "long-term-support" binary if others don't step up to also get involved.

Given FlightGear's constraints as a project (manpower, expertise, number of open bugs/merge requests, people with commit access, people able to triage bugs etc) it's actually very ambitious, not to say surprising, to even toy with the idea of releasing a LTS version at all.

If you start backporting the features, needed for an aircraft to the LTS, you end up with two next branches... more or less...
The idea was, to have a stable development platform for aircraft... so aircraft updates WOULD go into the LTS but for some aircraft, like the A320, they depend on changes made on next, so the LTS branch won't be updated anymore.

Personally, I actually oppose having too much of versioning and LTS... one stable and one next branch should be enough... with everything else, we waste resources.

Aircraft have already a flag for the minimum fg version. So you can't accidentally run a new aircraft on an old fg... assuming, the aircraft dev has set the flag right.

Right, that's exactly what happened during the early days of the plib/osg migration (~2006), and it caused ... quite a bit of irritation, even among some senior contributors at the time.

use the Plib branch is to *fix* the OSG code. Whining about it
is kinda bad form. People want to use the plib branch because
it works better than the OSG branch, and they shouldn't be denied
features just because it makes developers' jobs harder.

This is a big, disruptive change, and I'm sympathetic to you,
really. YASim and Nasal were big and disruptive too. But so
far, OSG has produced literally zero benefit for anyone.
People's experience has been anywhere between "it seems to work
OK" to "everything is slow and ugly" to "I can't get it to
build!".

For myself:

+ I don't like the OSG build system at all. Getting the
equivalent of --prefix requires 5 non-standard environment
variables to be set, and it doesn't support building
out-of-tree.

+ It's freakin' huge! Takes longer to compile than the rest of
FlightGear put together.

+ C++ shared libraries (12 of them). Enough said. I tried
the "make static" option, but it didn't install the libraries
properly.

And the biggest complaint:

+ No released version of OSG works with FlightGear, nor does
their CVS head. Technically, we're porting onto a *fork* of
OSG right now. We never did this with plib: if we needed
features from CVS plib, we'd still have compatibility code in
place that work work with their releases.

Since things tend to act out in endless discussions,
I went forward and take action, publishing the
