Product Field Settings do not affect fields on Product Class Nodes, Or Product Nodes

at /admin/store/settings/products/edit/fields you can set which fields are applicable to products. It is here that you can turn off fields like "image" "dimensions" "weight" "sku"

One would expect that these settings would effect all products AND all product class nodes too since there is no option to set these on a per-product class level. However these field settings do not effect product classes at all.

In most of my experiences with ubercart, i am creating a product class specifically BECAUSE the "product" does not conform to ubercart's notion of a "product". I am creating a ticket, or other event or class registration. These are not shipable. They do not need a SKU or any of the dimensions, for example.

Either these field settings should apply to products and product classes, or probably BETTER, one should be able to set "product field settings" on a PER-PRODUCT CLASS basis. On the product class "Edit" screen there would be a tab or section for selecting which fields are applicable. Additionally, a product class should be able to be set as "not shipable".

I would suggest that each product class should have its own:
1. product settings
2. product fields
3. product features
