Thinking about changes like that - we don't have to change the tag here for old natives. This change will just make old code throw tag mismatch warnings if the profiler is just stored in a Handle variable.

Are you sure? I thought that was handled silently.

Just the other way around of expecting a Handle param but passing a methodmap X < Handle.

methodmap CoolNewThing < Handle {
};

native void DoStuff(CoolNewThing t);
native void DoMore(Handle t);

public void OnPluginStart()
{
	Handle thing;
	DoStuff(thing); // warning 213: tag mismatch
	
	CoolNewThing newThing;
	DoMore(newThing); // ok
}
