I'm not sure it is a good idea to add a flag specifically for AIO.
Isn't it better to make it a configuration option, so any environment can disable it if needed?

No strong opinions about this, if we see other use cases to disable I think yes, otherwise I'd keep it simple that way and it is also what is used in other places like app_api
