Why do no emulators use mercenaries?

[Sandysham]

I thought that mercenaries were hard coded into the client. Thus, using them seems to be a no brainer over use of bots or even multiboxing. However, no emu server seems to use mercenaries. I am just wondering why? I am asking because I HATE having to box since it always seems like more work than play. Bots don't work well enough . Thus, if mercs are available, it would seem the much better approach to making the game more solo friendly.
