Tell me where I wrote that:

I already asked this question when Will made the same assumption as you
did, during the Fesco meeting. The use cases we had didn't include any
need for profile switching.

Yes we realised late we'd need it for some use cases, no, we didn't
decide to ship an unfinished volume control that we knew would impact
some use cases we didn't think of.

And we already knew that we'd need profile switching for some things
that we couldn't have before:
- out-of-the-box multi-speaker setup support
- multi-speakers testing
- Bluetooth audio profile switching and service reservation (eg. only
play stereo audio play through the headphones, and let a mobile phone
connect to the headset, music stops when you receive a call)

A couple of benefits from the current volume control compared to the old
- "default" input and output control
- microphone level checks
- sound effects level control
- per-application volume control (for apps that support it)

The only use case(s) that we haven't catered for are for people who want
to record things, and the sound card has more than 1 input. Yes, it's a
big omission, but that doesn't mean you're allowed to write off the
benefits we're bringing for a large number of users already.
