Actually, no it wouldn't, as the licensire would likely be tied with providing the service on a paid basis to others. You could write or maintain any codebase you want. Once you start consuming it for an employer though, the licensure kicks in.

Paid/subsidized maintainers may be a different story though. But there absolutely should be some level of teeth and stake wieldable by a professional SWE to resist pushes to "just do the unethical/dangerous thing" by management.
