Having said that, FWIW - I partially disagree with Jeron here - it does
matter.  A user can have browser extensions, multiple browsers (or mutliple
VMs with different OSes) and have a fairly good level of privacy if so
desires - as long as the underlying L3 provisioned does not prevent it.  Is
may not be exactly mainstream / commonplace, but not uncommon enough to
ignore (IMHO) either.
