The idea of "the domain for this repo" doesn't really match Git's
distributed model. A repo may have no remotes at all, or multiple
remotes with different domains (or even remotes which do not have a
domain associated with them, like local files, or remote helpers which
obscure the domain name).

It sounds like you're assuming that the domain would come from looking
at remote.origin.url. Which I agree would work in the common case of
"git clone https://example.com", but I'm not comfortable with the number
of corner cases the feature has.

I'd much rather see something based on the working tree path, like Duy's
conditional config includes. Then you write something in your
~/.gitconfig like:

  [include "gitdir:/home/peff/work/"]
  path = .gitconfig-work

  [include "gitdir:/home/peff/play/"]
  path = .gitconfig-play

and set user.email as appropriate in each.

You may also set user.useConfigOnly in your ~/.gitconfig. Then you'd
have to set user.email in each individual repository, but at least Git
would complain and remind you when you forget to do so, rather than
silently using the wrong email.
