I didn't want to bring up Linux, but yes, you are right.  I have
recently been packaging for Fedora and packages are rarely rebuilt --
only when there is an incompatible upgrade, or when the package itself
changes, the rebuild is done.  And, as amazing as it may sound, they
just work.  The fact of avoiding packages rebuilds over and over again
for no reason cuts down on resource requirements significantly.  Yes,
it has its cost in being less stable in some small cases, but it would
also result in the ability of building more packages, and keeping slow
architectures up to date.
