The existing package ecosystem is one of the main value propositions of Emacs. Otherwise a re-implementation with a different extension language could have replaced it a long time ago. > There are some small semantic differences but they could be handled by porting code. I suspect there are more than just small differences. And someone would have to do the work to port the code. I suspect that if packages that people use don't work, they will just avoid using the new version of Emacs, as opposed to abandoning the package. It's not an impossible project, but it's not clear to me it's easier/better than the proposed solution.
