I can’t even disable this Google bloatware on a stock phone (Nexus 5X)
Also, you've once again conflated "stock" with Google phone. If you use more precise terminology, you won't be so confused.
Yet I can still not disable these Google apps.

If you were able to disable the apps and then uninstall the the new launcher, your phone would be unusable until you did a factory reset from recovery.
And they take up space in my launcher.
Install something like Netguard (same dev behind Xprivacy) -- which functions as a firewall (vpn) b/w apps and the internet. Turn on logging. Watch all the apps you have installed phoning home and services like graph.facebook.com every few moments.
