I would say that 1X has had decent enough support. Sure early on it would have been nice for more already released games to get patched.Xbox One X is less than 3 years old.
And has, thus far, gotten a handful of enhancement patches. Certainly not any games that take full advantage of the hardware.
I promise you that owners of XBX do not feel like they have gotten sufficient content yet.
Current gen will still get decent support regardless of 1P for a reasonable amount of time.
I don't know what the general consensus is from 4pro and 1X owners are though to be fair, but I haven't come across much complaining.
