An update on this: The last part of covariance support has landed [1] a few days ago and is part of 7.4 alpha 1. As already described, full variance is only supported in conjunction with autoloading. When working in a single file or with explicit includes, the requirement that classes need to be declared before being referenced (including reference in variant type declarations) remains.
Does "only supported in conjunction with autoloading" mean that covariance is not (completely) supported when preloading is used?
