There are simply too many different extensions, and too many different valid combinations of them. A problem that is quickly getting worse, as there are a slew of extensions that are planned for final approval this year. The current set was defined before I started doing RISC-V work over 3 years ago, and I've been saying no to everyone that wants to change the default set. The current set is tractable for newbies to try to build and use. People that want a different set can define their own, and we have made it easy for people to define their own sets of multilibs as Kito pointed out. I do think that when the architecture profiles are adopted and implemented it would make sense to add them to the default set, and maybe eventually replace the default set. Jim
