I think we can include table like this one:

https://web.scheme.org/

But larger with more essential Scheme features, and those that implement
more of them will be on top. More mature Scheme implementation will most
likely implement all the features.

For some people the features will not matter. Only the language of
implementation and where it runs. For some they will pick the one that
implement most of the features.

We can do something like Wikipedia does for parser generators:

https://en.wikipedia.org/wiki/Comparison_of_parser_generators

we can indicate the supported feature with green and not supported with red
and partial with yellow.
