I don't know if it was disingenuous or not, but I think that being
able to improve performance would not be a bad thing. I've noticed
that a lot of things (like keyboard macros) are often slower than
expected in modern Emacs. We may, as a developer community, have
allowed the speed of modern hardware to lull us into complacency on
issues like performance. Emacs should be the best editor it can

I suppose this ties back in to earlier discussions about automated
testing (as, among other things, automated testing can find
performance regressions before they matter.)
