This is actually how most other packaging systems work. The main task
of the packager,
besides packaging itself and bug fixing, is to detect changes in ABI/API and to
update buildlink3.mk accordingly and make a recursive version bump (in
term of pkgsrc)
if necessary like pkgsrc developers did for png-1.5.
Nobody rebuilds *all* packages that depend on libX11 just because
it was updated. Really!
It's true that rebuilding packages recurisvely makes them more *stable* because
we don't rely on human's mistakes. But there are a number of methods
detect some kind of problems. In AltLinux, for example, (Russian Linux
not only required and provided shared libraries are collected (like we do with
REQUIRES and PROVIDES) but all *symbols* required and provided by every
executable and shlibs in the package. Package manager (modified apt4rpm)
in turn makes additional consistency per-symbol checks. More over
before releases they manually
analyse (and fix) problems their automatically ran tools detect in the
Rebuilding all packages recursivelly, especially in quarter branches,
costs too much
taking into account limitations in the hardware.
