What you want isn't playing vanilla 0.6 with 0.7 or 0.8 clients. What you want is a better mod system, that loosely couples the mod code with the vanilla code to make upgrading mods to higher vanilla versions a breeze.

Ideally an interface for a script language with multi mod support and on-runtime-drop-ins.
rachelfish: teeworlds has always worked like that. Major versions break compatibility. The only reason it's different this time is that 0.6 lasted so long there is a lot of old unmaintained content on 0.6
Sadly that would be years too late.
I actually believe there was a project trying to do this. Anyway, without the support of the vanilla dev stuff this would be no fun.

But yeah, something like Bukkit/Spigot for minecraft would have been awesome.

Just imagine combining every mod with instagib etc.

A second mod would add LordSk's InstaShields.
And a third mod would replace the laser by grenade launchers.
A fourth mod would add Catch.
And finally, the fifth mod Domination.

Oh and of course a mod that introduces smart bots.
I don't know much about that. I didn't day skins are game breaking, just that, like mapres, official skin parts make sense at major releases. There is little point in making it official if you can't rely on everyone seeing it, right?
after a while you can rely on the majority seeing it. Also you can rely on not having to install the skin if you use the latest version on a new device etc.
