Ubuntu Mate LTS with 5 year support?

[lah7]

Please see this post from the project leader earlier this year:

Why is Ubuntu MATE 16.04 only supported for 3 years, but not for 5 years?

Only Ubuntu and Kubuntu offer 5 year LTS, all the other flavours are 3 years. Which means we maintain/support the bit that are intrinsically MATE for 3 years, after that only the Ubuntu base system updates and security fixes will continue. We simply can’t commit to 5 years of support and point releases. What are you going to be doing in 5 years time?
