You are grouping two distinct changes together, and disparaging,

A small price to pay for stability. And what if pkg which (sqlite) is
more prone to
breakage, obsolete libraries, wrong compiler >> libmap... vs pkg_which
could be resurrected as a backup... I hope continually

One can easily have that now, pkg upgrading to ruby20 default when
ruby19 is still
installed or something... or my limited experience is not the norm

Portmaster handily handled the switches -d -B -P -i -g (ports unless
Why disparage that? Pure packages is not for everyone, and that in
itself AFAIK is a
feature not a bug of FreeBSD...

No disaster. Less
preplanning or experience, and your scenario may be right, but numerous
administering servers I've read over the years, and in FreeBSD books,
paint an easier and
more seamless sequence of events with each upgrade, most of each not
away from the command line, but line-by-line expertly managed.

I read reinstalling not a bad idea, but only in the problematic case.

Why 'very rare? ' I always thought that they were to work in tandem.
Isn't tweaking of
ports on one's machine consistent with knowing the ins and outs of all
the ports as well
as package workings? Make targets? etc.

But "this" here you have included both pkg (not yet seamless or as
reliable in my opinion) and the new scheme of abstracting away the
the smaller files. I see more bug reports from pkg (from here for
instance)... It seems
to early to call the above as a certainty.
Apologies if I am sounding way critical upon wishing to simply advocate
caution on any
divergence from the reliability the ports tree and legacy package served
for years upon
years. While pkg is saving time here, it has raised new fears about
the validity of my
recommendations of using pkg/ports to others... not having any poudriere
knowing how many low-powered routers pkg may not work on, having disks
not upgrade well with pkg2ng if ever... other unanswered questions.
