But if there are bugs introduced in the jump from 4.y.z to the new
major release 5.0.0 then they will be fixed in 5.0.1, and even more
will be fixed in 5.0.2, and so on.

In general 5.0.1 will not introduce any new features since 5.0.0, it
will only stabilise it and fix bugs. The same applies to GCC releases.
So your reasoning that keeps leading you to x.y.0 releases is
seriously flawed. x.y.0 is invariably the worst of all x.y.z releases.
