I doubt it. This PR uses a test double instead.

client.on('error', (e) => { throw e; });
const req = client.request({ ':path': '/' });
request(req, client);
req.end();

nit: ':path' defaults to '/' and, when using a GET request, the req.end() is unnecessary because http2 will automatically end()... so this can be simplified to:

request(client.request(), client);

I added a comment indicating it's 'HTTP' for now. Hope that's sufficient. (If we ever need a test double for https, only the comment will need updating and not the code.)

this requires a manual backport to 8.x and 10.x

should it be backported?

Low value. I'd say no.
