Sure, feel free to file an issue at GH. I might implement it.
I had a cursory look: Does one get unlimited (or very high) requests with MobyPro?
The only number I was able to find is 720 requests/h (https://www.mobygames.com/info/api/#limits) which is low in contrast to a paid screenscraper access of same value.
Many things MobyPro offers are of no use for scraping / Skyscraper anyway.
I am also not sure if I am fan, that ~MobyGames~ Activision/Microsoft is trying to monetize community created value.
