You are a Ubuntu user. I am a CentOS|RHEL user.
There support is 10 years.
Check this: https://wiki.centos.org/About/Product
Official party line here:
CentOS6: until 2020 for maintenance updates
CentOS7, until 2024 for maintenance updates.
Using the recent/latest is possible with e.g.
* Software Collections https://www.softwarecollections.org/en/
If one needs a 4.x kernel that is doable too via elrepo. But there is a lot
of backport happening by RedHat. There is a reason these guys are making
gobs of money: they support business.
Frankly I wouldn't touch Ubuntu with a 10 feet pole anymore now that I have
100+ servers running CentOS under management.

To be frank 14.04 is the only decent release I know. All of the other ones
have issues of one kind or another.

Sure. But change is to be managed and the business is what makes money. So,
not catering to business needs is a losing proposition.
There is this business by Clement and Esteban that apparently will come to
life at one point. I guess business forces may have more impact at that
time frame. Wait and see.
