That's actually easy to fix. .15 has learned the new flag
PA_STREAM_DONT_INHIBIT_AUTO_SUSPEND. If you set that on a stream then
the stream is ignored when the auto suspended decides whether a device
can be suspended or not.

It's just a matter of setting this flag for all streams pavucontrol
creates. Patches welcome.
