[plt-scheme] running an MzScheme debugger in Emacs?

I wonder what led the emacs development down the cul-de-sac of 
embedding everything that can use some editing functionality into 
emacs, rather than making emacs an embeddable editor component for 
other programs (one of which would be the programmers' editor). Even 
assuming that was a valid design choice back than, its highly unlikely 
that it is still so.

As an example, Scintilla and its ecosystem of editors based on it, 
seem to offer a much better return/effort than emacs since their 
developer teams are tiny compared to people working on emacs, yet they 
offer fast, native UI, customizable editors running on multiple platforms.

It will be interesting to see what comes out of MS's "emacs clone" 
project.
