These are not realistic replacements.

These sound like great options to add in the future, such as:

   --perf-test: Run performance tests on your repository using different
   Git config options and recommend certain settings.

(This --perf-test option would be a great way to get wider adoption
of parallel checkout, since its optimal settings are so machine
dependent.)

The thing is, even if we did these other things, it would result in
some kind of document that summarizes the repository shape and features.
That kind of data is exactly what this version of 'git diagnose' does.

For now, it leaves the human reader responsible for making decisions
based on those documents, but they have been incredibly helpful when we
are _diagnosing_ issues users are having with their repositories.
