 Although we haven't written it this way, the current scheme gives a EOL of 'next LTS + 18

Does the release of an LTS include minor releases, is a release of 4.9.x
an "LTS" release? Or is a 4.x an LTS release. My understanding was, that
4.x are new "releases".

My concerns are, we can not guarantee 2 LTS releases per year, can we?

Predicting the future is hard and we should have a more "relative"
sentence how long we support it.

In my opition, there should be an overlapping of support time for at
east 6 monnths (that is why I added +6 months).

What would it cost to change the support time of an LTS like:

"6 months after next LTS release (minimum 18 months)."
