Assuming backwards compatibility is reasonably safe (gcc does it for  
as and ld all the time), never been much a problem.

I think it is best to avoid the time hit at runtime.  As for the  
general idea being worth it, if it works well, if the plugin is stable  
and improves codegen...  If the user experience is horrible, better to  
default it to off.
