Let us do that in two steps.
Now: add an alert Window if someone chooses ESD in the session profile. in 6-12 months: remove the feature.
Something like that was implicit... sure, I won't delete it right away. Actually, I was interested in user opinions. There's no way I'd even think about removal if there are legitimate use cases out there (and for what it's worth, testing indicates that ESD still works fine via the PA esound emulation in the client.)
Best regards,
