Almost.  The exception is that you may remain on an older hardware
enablement stack until you take explicit action:

No, this has nothing to do with the enablement stack stuff.  If you
aren't seeing /etc/lsb-release being brought up to date, then your
upgrades aren't actually happening and you need to investigate why.

In general that's not possible, because not all the packages from older
point releases remain available from the networked archive.  To install
an older point release, you need to install from corresponding
installation media.

debootstrap will bootstrap from trusty without trusty-updates, which
corresponds to 14.04(.0).  You can then apply updates on top of that,
which will get you to whatever is latest (not necessarily the latest
point release, but rather rolling stable updates).  You can't get to a
specific point release this way.
