Question about Plugins and the need to update a plugin.

I was wondering if Craftbukkit will end up having the same issue as hMod where certain updates forced the user to have to recompile the plugin maybe sometimes more?

The big question is Craftbukkit going to be the same? The other question is why is there a must for a person to have to be forced to update their plugin? Is there no way to program a base system that allows upgrades and such and still be able to use old plugins and hooks and such?

I'm no programmer but maybe someone can explain this to me. (I'm of course not going based on what goes on now since the second someone pushes an update it breaks but then again you guys are adding hooks daily.


Also will there be anything like whitelist, limited special commands and such with bukkit and also a bukkit config file or will it be and act like vanilla and everything will be plugin based?

Just wondering because I don't know if I be forced to rely on plugins that might break and then more delays during update days <3
