so it's a choice between abusing a pre-existing location but standards
specified for another use, or using a non-existing location with no
standards whatsover.  can't say i really like either option.  more
specifically because both are not addressed in policy/fhs, i'd be worried
about an in-flow of non-standard, first-come-first-serve namespace
