No, I've only sold them when the .com is taken or well above they're budget. But I have seen sites get reg'd and Dev where they left / forgot / or did not bother with .com lol...most WILL take .com ....Bundles have never worked for me...in any niche....they always just .com.....this niche is different that, smaller builders have no issue building on .xyz .io and when priced out on .com .....They are many dev Ordinal sights on all 3 and the .com ones ..when I said KILLER keywords (+Wallet) good example...like OrdinalWallet.com is all ready Active and Developed....
Of they 3 it's been my experience, they will pick what fits their budget and try to include the .com if able ....and if not...they will build on the other 2 and upgrade down the road IF they grow....
