I don't think the comment you are responding to means that Oracle should make something like WSL. It is probably saying that WSL2 requires hyper-v to be enabled which prevents Virtualbox from running, and it would be good if Oracle had a workaround for this.
This. Vbox won’t run if Hyper-V is enabled, and Docker / WSL2 won’t work without Hyper-V. True for me on vbox 6.0.14, it just crashes the VM with a cryptic error.
Workaround is not easy, hyper-v had a different feature set for networking and shared folders (not sure the latter is directly possible) as well as using different disk image formats.
