Do regulatory concerns prevent TF from selling XTZ in the tzBTC/XTZ pool?

It seems pretty clear that regulatory concerns prevent them from providing liquidity in that pair, would selling xtz in that pool be seen as materially different from asymmetrically providing one-sided liquidity, from a regulatory perspective? It seems like the only way this could be permissible from a regulatory perspective would be with modified protocol such that xtz was asymmetrically added with no return of tzBTZ, similar to liquidity baking but from TF rather than inflation?
