And we also see that they have not yet 'hard enforced', but it looks
like some trigger on a domain results in requiring SPF for that domain.
Of course, we don't expect Google to reveal their secrets, but we can
assume things like new IP(s), new domains, sudden traffic surges, or
customers clicking on 'this is spam' all might cause the requirement for
SPF on a certain domain.

Hi,
Well i have no SPF records. See [doraji.xyz <http://doraji.xyz>]. And
all incoming emails go
to Gmail(soyeo...@gmail.com <mailto:soyeo...@gmail.com>) by
forwarding. The Gmail is my final inbox
provider. Really there are no troubles, at least, to me...
My observation is that Gmail enforces authentication via SPF or DKIM
since the first days of march 2022.
One of SPF or DKIM is sufficient to get mails delivered to Gmail.
It looks like Gmail imposes a DMARC policy of reject for every sender
domain ignoring the actual DNS entries for DMARC or their absence.
We just did 2 tests, one with an email that violated half a dozen best
practices and one that has a SPFSoftfail (with no DKIM).
SPF SoftFail delivered to spam:

This message probably shouldn’t have been accepted. The number of spec
and best practice violations is extremely high. But it, too, ended up in
my spam folder.
