Why exactly are they broken?
Sure, it will force the user to choose between installing this and
having the latest version of the package installed. But I don't see this
being a problem.
As an example I always get this on world updates:
WARNING: One or more updates have been skipped due to a dependency conflict:

Fact is that sci-mathematics/sage can't be made work without those deps.
Fact is that I want this package and couldn't care less if I have the
latest version of these other two packages.
If in turn I cared for the other two packages, then I would have to
remove sage. It's a choice but nothing else.
And before some asks, no portage wouldn't break this dep these days:
# emerge -1u --ignore-default-opts -vtp pexpect
These are the packages that would be merged, in reverse order:
