branch updates - strategy change?

[Greg Troxel <gdt%lexort.com@localhost>]

I'm now using bob on my build machines (domU per version/cpu, for
versions I'm running, and the next one I'll upgrade to), and am seeing a
lot of builds/changes on 2026Q3.  I more or less suspect this is an
artifact of "bulk rebuilds always" vs "pkg_rr rebuilds if a dependency
version changes".

After cvs update along the branch, and a bob clean/bob build, I see that
there is a vast amount of packages to rsync, and then "pkgin ug" wants
to "refresh" about 200 packages and upgrade:

  expat-2.8.5 pcre2-10.49 png-1.6.59

These are pretty obviously micros with security fixes (rather than fixes
as patches).


I wonder if updates to the branch are different, or if this is just the
usual bulk practice being super aggressive about rebuilding.
