No. They don't do security updates or new features, unless they REALLY have to.

Security provided by network separation and features are usually provided by new systems working in parallel with old systems.

Some utilities even stockpile hardware, so that they can replace failing components with hardware from the same batch.

Not just utilities. A few years before Y2K I visited a client, a printer, and they showed me a dozen Sun3 (yes 3) stored in a room. They had some software running on SunOS 3.5 that they planned to replace in the next decade or two but for the time being, they needed it running. Their Y2K fix : switch the system clock 28 years back and a bit of scripting.
