Bear in mind that even though the LTS version T8 is based on is a year old it
will also be supported until 2021. That's a good long while down the road so
when it's finally done it will be a long time before absolutely needing
replacement.
I believe Trisquel is a mixed-use distribution which is meant to be used for
both a desktop and server. It is meant to be used by individuals, schools
and businesses alike. Many of it's users are looking for stability and
quality and not just the latest features.
Just my two cents.
