It depends on what Google mail server you are sending to. Some require SPF, some don't. Although, maybe they've since closed that loophole. Google started requiring SPF records back in December 2021 according to the logs I reviewed (at least for some of their mail servers). The mail servers that don't outright reject messages without SPF may be putting those messages in the spam folder - I can't really verify that.
I'm a little surprised people are this upset. Google's using SPF for what it's actually meant for - and yet people are upset because they are doing that? What's the point of adding all of these anti-spam and anti-spoofing measures into SMTP if you're blackballed for actually using them? SPF is a great tool to prevent spamming and spoofing - but it depends on the sender knowing how to set up a proper SPF record (as in knowing exactly what mail servers their domain name is sending out from). But very few people know how to do this (or care to know). I see Google embracing this as a good thing. It's telling people that they need to know what they're setting up and set it up properly. Otherwise, don't complain about the spam/phishing/spoofing that continues to go on.
