I remember it differently, as I rarely encountered office networks then, and when I did, they were still 3rd party (Netware mostly).

The reason I always remember 3.1 is that 3.0 was a "big" upgrade, but it was a dog, so they released a vastly-improved 3.1 pretty quickly, so many people got that as the default, and the upgrade was pretty widespread.

This was over maybe a 4-year period in the mid-90s. My memory may be hazy, and I was a university student, so my exposure may have been limited, but myself and my friends never really reference 3.11 because it wasn't used/needed, and indeed most of us used Trumpet Winsock as a TCP/IP stack (3rd party) until the release of Windows 95.
