Yes, you are correct here. For the user within emacs, its just that
the effect on the programmer is probably more of an issue that the
optimisation. 

Obviously if fixing the former, gives you the latter for free, then
this is a good thing.

A reasonable assumption in the context of emacs!

This is certainly true. I can imagine a emacs based web server would
be quite nice, as you could use all the emacs based formatting
abilities.

I think we are in furious agreement here!
