It wasn't an absence of a market. Those of us that had to manage OSX Server soon found out the software was marked by several high-profile bugs, technical debt, and a perceived decline in reliability. I migrated a large number of Macs to Ubuntu Server software. The hardware was great.
I fear the quality of macOS is deteriorating today in the same manner than befell OSX Server.
