in order to occupy around 1mb of ram memory you need an array of 20-30k entries so its safe to say that memory isnt an excuse not that it ever has been something to consider especially working on mods for games.
the last major update admincmd.sma file has had was when 1.75 was introduced according to some sources and this was in 2007 or 2008. since then there've been minor edits and additions. theres no such cases as players having STEAM_ID_LAN on multiplayer, unless you account for reunion or dproto which is against ToS.
