That sums it up
Frank, your description of "non-man made error" pretty much sums up my thoughts on what should or shouldn't be listed as a variation, though I've never used that terminology.
The 1956 Schmidt will not make the cut as a listed variation.
A few cards, like the Herrer and the 1990T Frank Thomas no-name have been grandfathered because of their value/popularity.
The T206s you mention are not included in the Standard Catalog set list for T206, but rather have a separate listing along with Sweeney no B, etc.
