Even for a system with bluez installed, it would be nice to have some option that could disable this support when it's not needed. As bluetooth snooping can be a method of privacy invasion, and a misbehaving app could cause issues with the native apps running on the host.
If you're concerned about that, a setting in Wine won't save you. We don't do anything that requires special privileges.
The main thing I'm more worried about is something similar to the following:
End user is talking with their boss via bluetooth. User runs some Windows app under wine. The Windows app hits a wine bug and tries to reset the bluetooth controller as a result. End user is accused of "hanging up" on their boss.
Keep in mind, the same thing could happen with a potential wifi driver. (And in fact is far more likely to occur.)
Having a means to turn that support off would at least mitigate the risk of such occurrences.
