[db-wg] Historical records... what is and isn't available

I bumped my head on something unexpected a day or two ago, and I would
now just like to ask a question, to find out if what I seemed to see
was just a product of my own programming mistake, or if it is fact the
way things were intended to be.

So, true or false?  The --list-versions and --show-version options are
not supported for person:, role:, and mntner: records.

To be clear I am *not* asking if the data returned when the --show-version
option is applied to one of the types of records I've just listed is
merely redacted of all personal information relating to natural persons.
Rather, I am asking if I should in fact be expecting to get absolutely
-nothing- back when/if I try to use --show-version on any of the
aforementioned record types, regadless of of whether the requested
historical information contains 100% personal information or alternatively,
if it contains 0% personal information, or anything in between.
