Your example was quite good actually. Even in sw the people that build the system is not necessarily the people that monitor, maintain and use it, even for systems used only inside a company. I used to work in a telco and we had 3 separate departments, plus a 4th one for testing. And yet all of them seem to be subject to section 174, builders, maintainers, testers.
A country wide power grid or telecommunications network are other examples that come to my mind. They are never complete, they get more features every day (new cables?), they are monitored 24/7. The owner companies also use them.

Upthread one can read: > Activities that are not treated as software development vis-à-vis software developed by a taxpayer for use in its trade or business are as follows: […] • maintenance activities after the taxpayer places the computer software into service
