Of course, anything deployed for use by the target customer is a production system. And anything that is under development is a dev system. Pipeline itself is not under development and it is in use by the target customer (developer). What's the confusion here?

Acknowledging that developers are in fact customers, is often where it comes undone in my experience.
In a lot of places, only revenue paying people are considered customers, everyone else is a cost centre.
Dev tools are often seen as a tax the business pays to be able to generate revenue. Investing in them, or treating them like the production level systems they are, isn’t intuitive for most, and for some a hard cost to justify.
