And then some applications randomly break because of an ABI change.

Recompilation has been known to randomly break applications as well. The art of a good security patch is that it doesn't change anything besides making the security fix.

Uhh.... Whut? Recompilation can't break applications, especially with repeatable builds. A bad fix that changes the API can certainly do that.

But it's way better than random breakages because the ABI has subtly changed.

If the compilation is needed due to a change in a dependency, it is not a repeat of the previous build. If it was, there was no point in recompiling it.
If the compiler has changed, the recompiled application may behave differently, too.
