This is all fine, but seems to totally miss RMS' point. We can debate default settings, type handlers etc as much as we like, but I think Richard's point was that since we are introducing a new feature, lets make it easier for the user by calling it someting obvious rather than the more cryptic. Using 'eww' may be considered 'cute', but it certainly isn't 'natural'. You will have to put in real memory effort to remember that emacs' in built support for web browsing is 'eww'. Sure, with the great searching mechanisms of emacs, most users will be able to find this procedure fairly easily, but surely it is better if they don't even have to look or use any effort. This is especially relevant for a feature like this which is unlikely to be used by a lot of people every day.
Years ago, I had a real problem remembering M-x ielm. Because I only used this command occasionally, I was never able to remember it. Even with apropos et al. it often took longer than necessary to get the right memory jog. Using names which are as 'natural' and reflect purpose as much as possible will help and certainly won't make things worse.
