ISSUE-41 covers a particular family of proposals for additional  
extensibility. Some of those proposals may build on the already  
existing extensibility mechanisms. Others may propose brand new  
additional mechanisms. Some might even propose removing some of the  
existing mechanisms in the course of adding new ones, though I do not  
believe anyone has actually advocated that view. My hope is that when  
ISSUE-41 is settled, we will have a good picture of the overall range  
of extensibility mechanisms we plan to offer, and how that lines up  
with the charter's encouragement.
