Github updated to allow adding product to 1) check that the attributes of product being added to the cart are in fact defined by variants present (all listed as a combination in one variant or each attribute listed individually), 2) to manage at least the special cases of fill in the text and upload a file (welcome input if other attribute types are an issue), and 3) for product presenting a text field or upload file when Dynamic Dropdowns is disabled.

Next up, to support the code disabling dynamic dropdowns for the product that do not display accurately for the attributes applied to the product to allow maximum use of the features while development continues to make the dynamic dropdown part more robust.
