For now, console.profile is only supported with the old DevTools performance panel, otherwise it has no effect.

At the moment, we will simply start showing a message to users when they try to use console.profile with the new panel. Before trying to bring the feature to the new performance panel, it would be great to know if the feature is used or not.

In Chrome DevTools, console.profile is still supported, but you need to open a hidden panel in order to retrieve the profile. It doesn't seem like there is first class support for the feature.

We might add some telemetry to monitor this but in the meantime, feedback on this bug would be useful.

Changing severity to S4 because it's not on our critical path to shipping the new proifler to release.
