Mike provided the insight that NodeInfo ties user identity to a single
specific instance for the purposes of total user counts and user
activity.

custom pairs of `(activity counts, time period in days)` that make sense for
the software.
* The `usage.users` assumes that user identity is tied to a specific instance of
running software. It is unclear how to count `total` users when user identity
is: spread across multiple servers, spread across multiple groups, or present
within multiple collections of users. Multiple software instances could each
have a resonable claim to counting the user as "using" their software, which
globally results users being counted more than once.
* The `usage.users` activity counts likewise assume that user identity is tied
to a specific instance of running software. For the same reasons above, where
the `total` user counts may result in duplicate counts of the same user across
all software running, the activity counts `activeHalfYear` and `activeMonth`
may also result in a globally inflated count.
* The `activeHalfyear` and `activeMonth` are ill-named properties for describing
the time periods of 180 days and 30 days, respectively. A "half of one year"
is 180 days 0% of the time and roughly 182.5 days only 75% of the time. A
