For upstream dialects registration is sufficient because the auto-loading mechanisms are infallible. That's why I proposed this version rather than the one alluded to the issue (in terms of loading) because this version can indeed be a side-effecting import, which as you say is very fine UX.

That's doable since now the default registry is an exposed global.
