Do metadata tables have format versions? I would argue no?

Yeah I don't think it makes sense for metadata tables to have a format version. The entries in the tables could be spread across different "versions" of a table where the underlying table had different format versions.

so the only table where this would be currently necessary to have is PositionDeletesTable. This is so that we can know in SparkPositionDeletesRewrite (which runs against PositionDeletesTable) whether existing position deletes need to be rewritten to either V2 positional deletes or to DVs

I think the API makes a lot of sense, it'll shrink all the awkward call points which cast to HasTableOperations just to get the operations. The only doubt I have is if it makes sense for metadata tables to have this API. I don't think it makes complete sense since a metadata table could have entries which span different format versions for the underlying table
