How to disable spectre mitigations in Fly micro VM kernel?

How would we be able to set “mitigations=off” in the built Fly VM kernel so that it runs with faster performance?

This is not currently something we’re set up to let apps on Fly.io do. We’ll keep it in mind!

If the host kernel is running with mitigations enabled, do the micro VMs even need to run with mitigations as well?

Seems pretty similar to the question of whether a browser needs speculative execution mitigations. Again, a thing we’ll keep in mind moving forward.
