That's up to each server owner to decide, as he/she pays the bill.
Same as the first years of original Renegade (up to 5 years or so), I'm sure there will be plenty of servers with different game modes, and you'll be able to find at least one server you would like to play. I personally prefer marathon games, and servers with few specific modes, like weapon drops (when done properly, meaning no ramjet and timed c4s to SBHs) and the upgraded crate system (jelly marathon server for example). You really can't tell me my preference is less legit than yours.
And if you don't like any of the servers, than by all means, rent up a server of your own.
There isn't a global-ladder anyway, don't see why it should bother you whether people play one gamemode or another., doesn't affect any of you..
