As a VR dev…Nanite has no current value due to not yet being supported in VR. I do purchase non-VR assets for use in VR as there is usually no problem in doing so…but Nanite will start to become an issue if I have to continue to disable it in order to initially use an asset.
What needs to be done is creators of assets need to either supply both Nanite and non-Nanite versions in their folders or give a user the ability to download a non-Nanite version only if Nanite is unwanted.
