Well, I had enough discussions - with you as well - about the LTS model.
Answers like ‘…we do not really care to upgrade on past release.’ as from 127 security vulnerabilities installing tryton-sao 5.0.x (#9117) · Issues · Tryton / Tryton · GitLab is not what I expect from a well-maintained LTS model. This discussion around the Werkzeug ‘Patch’ was another bad example. Trytond 5.0 compatibility with werkzeug 0.16 (#9042) · Issues · Tryton / Tryton · GitLab
In my opinion, I dont see that 5.0 will run in 5 years time on a reasonably up-to-date system.
‘What we can do to improve’ was subject of a larger discussion in April in the foundation mailing list. You may want to review this
