It's not Intel's issue, it's a design flaw per se, affecting _all_ CPUs that use predictive branch execution that has effects on the processor cache, which are pretty much all processors produced in this millenium.
That said, there _might_ be a solution to this problem in a way that predictive branch execution does not need to be removed completely from future architecture, which would be a thing we don't really want to loose, even if it increases safety. During that time, it makes sense to disable it, but not by default. The only implication is that older systems must be patched, which is every admin's responsibility.
