Has anyone measured recently whether there's still a significant perf win to making IIDs 32-bit? If we stop using them as a versioning tool, we could potentially relax our uniqueness requirements, and save a lot of comparisons on each QI. Addon-compat would be tricky, but is potentially solvable.
It may be that we've optimized enough stuff that we don't QI on the hot paths anymore. But it might be worth a day of someone's time to check if it makes any difference on Talos.
