Ooh, I see what you did here. Clever 😃.

For consistency, I'd probably move these to _applyCalculated. I know it's not particularly interesting since you said we don't report telemetry but it's still conceptually cleaner. You could just put this in _applyCalculated():

    if (this._isInServerlessEnvironment()) {
      this._setValue(calc, 'profiling.enabled', 'false')
      this._setValue(calc, 'crashtracking.enabled', false)
    }

[rochdev]

Ironically, I moved them here for consistency, as other options are also calculated in this way in _applyEnv. For now let's keep it there and we can revisit in a separate PR if needed, although I kind of think it makes sense to be in _applyEnv as Serverless is an environment. In any case, I'd consider this out of scope of this PR since there are other occurrences.

[szegedi]

I thought "Env" in "_applyEnv" meant "environment variables". But you're right that some uses of specifically _isInServerlessEnvironment have already snuck in, so by that reasoning I can accept these being there as well. If someone gets sufficiently irritated by it, they can fix it later.

[szegedi]

Looks good for profiling.
