If I'm understanding you correctly you're saying it's an issue when I do:

pkg_add A B C

# 1 year passes

pkg_add D

# D depends on A, B, C, of different revisions. pkg_add barfs because
it can't find the applications, etc.

This is something that's been hashed over a number of times (a few of
which I've participated in in #bsdports). There needs to be a simple
update command which will handle the action of upgrading packages,
because there isn't a proper command that will do so today.

Unless PBIs are self-contained entities which have their own sets of
dependent utilities and libraries, etc (which you weren't suggesting
in the sentence above), or install into a common location with
versioned directories (which is a pain in the ass and involves a lot
of hardcoded pains dealing with libtool files, libraries, etc -- been
there, done that with Gentoo Linux -- there are hack scripts written
to work around several possible hardcoded version issue, and there are
a handful), AFAIK there's nothing positive and new that PBIs can bring
to the table in this regard that can't be implemented in pkg_install
as-is, other than the point-click-install user-friendly interface.

Yes, but if I now have to waste more bandwidth and disk space
installing packages, why shouldn't I go to another operating system?
Switching over to PBIs will reel in more desktop and entry-level
sysadmins, etc, but I fear that it will isolate folks in the embedded
market as well as several more seasoned users because of the
implications involved with the extra bandwidth requirement and
footprint.
