OpenBSD and DragonFly had their meltdown mitigations done in a couple of weeks from when it was publicly disclosed. If it's good enough for projects developed by handfuls of volunteers, it's good enough for the multi-hundred billion dollar megacorps.

So you're saying if a small software operation can put in place mitigations in X time then a absolutely massive hardware operation with hundreds of product lines consisting of some of the most advanced, ridiculously complex, slow to develop chips in the world can push a fix to many billions of devices in X time as well, whilst ensuring backwards compatibility and reducing the performance impact across the mind mindbogglingly large number of different workloads that their chips are used for.

Makes sense. 90 days is more than enough.

Implementing KPTI didn't involve any of what you just said.
