Gmail registration now requires scanning a QR code and sending a text message

I have tried it myself, the registration is no longer possible with the QR code. Supposedly, using the QR code on the smartphone triggers an SMS sent from your phone to Google in order to verify your phone number. Supposedly, this is for security. A valid argument, since finish is harder this way, although not impossible. However, this prohibits the use of services like SMSpool, too. Does anyone have any ideas how to handle account registration in the future?
