You can easily host and manage your own package repository. My point is that this apparent limitation is not in itself a strong enough reason to embark on NIX.
Go fill your boots if you want to use NIX, power to you, but be honest about why if you're going to write a piece about it.

Sure, it's not hard but it's work nonetheless, plus you'll incur the costs of maintaining that infrastructure indefinitely. Compare that to creating a Dockerfile which uses https://github.com/reproducible-containers/repro-sources-lis... to fully pin its package sources and calling it a day.
