Miscellaneous: /who all zone was a GM command during the time period Project 1999 emulates.

/who all zone was not available to players until years after Velious, and so it should not be available to players on P99.

I've compiled a small list of evidence:

We will not being seeing a command to see who is in a zone at all (it was hinted a while ago that players might). It's a shame really that we aren't.
This functionality already exists for those who are GM flagged, however due to bandwidth and server load issues, we've decided not to open it up to the playerbase at large. This command has to query the server of the requested zone in order to return the list.
Dozens of people on each server executing the command at the same time would presents the concerns mentioned above.

In the below link, in this guide from 1999 on all of the in-game commands, there is no mention of a /who all zone functionality for the /who command.

this is a very broad command, basically the /who command just tells you who is in the zone. While the /who all command tells you who is in the game world. You can also use it to find specifics, for example you could type /who all cleric or /who all cleric 50. The first one would report how many clerics are in the world, the second would report how many are level 50. You can also do this by race or race/class, such as /who all barbarian rogue or /who all gnome necro. Abbreviations work fine most of the time. You can also do /who all friends to see a list of everyone who is on who is on your friends list. Or you can do a /who all GM to see any GM's on, if they are not in inviso mode =)

In the below link, in a google chat group post from Dec 5, 2001, it is explicitly mentioned that a /who all zonename command does not exist.
