I just bought a computer from newegg with bitcoin and I think they used bitgo. They also had the 15 minute window thing. But the transaction didn't have to be confirmed in that time. It just needed to be out there somewhere which only took about a minute. And that was back when BTC was around 15K and it would takes hours for a actual transaction to be confirmed. But it would lock in the transaction quickly and then it would take a while for newegg to send me a email saying the payment was confirmed.
I just checked and the time between my order and initiating the sending of BTC to bitgo in Electrum to newegg saying the payment was accepted was just a little under five hours.
Bitpay and Coinbase's old merchant tools both already use a 15 minute window. Not sure what Sprite is but most likely the influence was the other way around.
