My interpretation of this was that it would be something like the Firefox
model. As Mark's blog states in more detail, the idea is for all releases
to be production ready and, indeed, for the development mainline to be
more stable in general, so big features would only go in when they
are ready to go out (implying they need to be tested heavily elsewhere)

So I see it more as distros like Fedora would pick up every feature
release, while something like RHEL would use the long-term
support release. I presume update releases would be made available
for both; basically the equivalent of the current security releases
on the same cycle. So, October 2018 & January 2019 would see
just the security update for the long-term support release, 18.9, but
April 2019 would see security updates for both 18.9 and 19.3, the next
feature release after the long-term release (assuming updates stick
to Oracle's product-wide quarterly update cycle).
