Instead of integrating the library as a whole, I'd prefer we extract
those features from Helpful that people think are useful and not already
available in Emacs. I don't think that having two separate help systems
in core is a good idea, there'll be too much duplication and maintenance
burden.
Showing references to a symbol is an interesting feature (for example,
to learn how to use an ELisp API by looking at examples). I see that
Helpful provides this feature via the separate package elisp-refs
(https://github.com/Wilfred/elisp-refs). The closest package I know
that actually understands ELisp is el-search from ELPA, but elisp-refs
is a more specific package for the concrete use case of searching for
references.
If we can get copyright papers, perhaps we could start by integrating
the functionality of elisp-refs as an xref backend. Then the help
system could use the new backend to provide a "References" link button.
