@charlypoly thank you for this contribution, this is amazing!

However, the reason we extracted drivers out of the "core" package is that we wanted to expose a mechanism that would let other community members integrate custom drivers that we can't maintain & keep under the official organization (mainly due to the limited team bandwidth & time). Bringing another driver in would decrease our velocity even further (and given the amount of packages & drivers we already maintain, it's getting more and more difficult).

So in this case, I'd rather suggest creating a new repository & new package and publishing it as a separate community-driven OSS package. Once it's published, definitely let me know and I'll make sure we mention it (add a dedicated section in README/maybe docs too?) and link it here :)

@kamilmysliwiec thank you for your feedback, we will proceed as you stated.
In the meantime, could you review and publish this change proposal that is required for us to integrate with @nestjs/graphql: #2156

Thank you!
