I read this PEP and some of the discussion.

The difference to my idea is not to propose a LTS version and feature 
preview releases.

The simplest form of my change is to switch from today major.minor to 
simply major for the feature release cycle.
Additional minor feature releases for the standard library can also be 
optional or limited to provisional parts of the standard library.
In all cases they should be backward compatible.
But have the option to change the Python parts faster than the core.

My idea came up because I have seen the need to improve the standard 
library in a faster pace than the core language. And to show this also
in the version number.
Hopefully ending the if it is included into the Python standard library 
it will be dead.

Resulting in more releases but for the core with the same release cycle
as of now. The amount of minor releases is not high it will be kept
lower as it is now.

Another point is to show by a higher major version number how mature 
Python is. (marketing) ;-)

For Linux distributions there is still the option to include a
specific Python Version with a feature set and recommend it.
If someone wants to be conservative it is save to rely on features
only for the first major version. This will be the same as of now
for major.minor.
