KHR_materials_diffuse_transmission schema is not a material extension?

Is there any reason why the extension is defined as:

glTF.KHR_materials_diffuse_transmission.schema.json

"title": "KHR_materials_diffuse_transmission glTF extension"

is not named as:

material.KHR_materials_diffuse_transmission.schema.json

"title": "KHR_materials_diffuse_transmission glTF material extension"

like the rest of the material extensions?

Start by comparing glTF.KHR_materials_diffuse_transmission.schema.json and its title with the other material extension schemas named in the issue. Check the repository's schema references or validation entry points for assumptions about the filename. Done means the naming and title consistently follow the material-extension convention, or the repository records why this extension is intentionally different.
