I believe you mean (specifically) cut off from access to GMail
send/receive access by GMail users, as an alternative to using GMail's
proprietary WebUI. Yes, that's very strongly my understanding, too.

Of course, my own way of eliminating GMail problems is: Don't use
GMail, and you thereby magically avoid GMail problems. ;->

This does _not_ accord with my experience. In my experience, if you run
a spam-clean and RFC-compliant SMTP operation and take modest
anti-forgery measures (such as my domains' strongly asserted SPF RR),
your mail domain will have no problem bidirectionally communicating with
GMail / Googlemail -- without spamboxing or teergrubing, etc.

I keep monitoring this situation, and it may change, but that is still
my honest assessment from many decades of self-hosted SMTP smarthost
operation.
