Generally I like this idea, but two questions about this:
Where would we put the "canonical" copy? Somewhere on github might seem logical - maybe even the style guide repo itself? But it could also be somewhere on the STScI web site.
Are there subtle legalities or something we should be worried about if we don't include the text a la how it might work with licenses? (I think not - as @pllim pointed out plenty of other projects like Astropy use this - but worth asking at least...)
In https://github.com/spacetelescope/style-guides/pull/38#issuecomment-415524496, @pllim (+ @stscicrawford) pointed out that having the Code of Conduct be a link rather than full text might make life easier.
