I think some of these could be interesting if they deviate from the
default (e.g. "in_hot_standby") as it will give the user context on the
current state of the system.
However, something like that is still fairly easy to determine (e.g.
`pg_catalog.pg_is_in_recovery()`). And looking through the settings
marked "internal" showing the non-defaults may not provide much
additional context to a user.
+1 for excluding them.
