This is so obvious, that I believe they won't build it intentionally in this phase of coin.
Having GUI wallet for windows or not, at the current period, does not matter. The main reason (in my opinion) is Grin coin has decreased to its very solid foundation of price, and it get good demands in current range around 40000 satoshis. Hence, I believe from that range, Grin coin will solidly recover, but its recovery will take time to fully confirm and finish.
