Three Years of Nix and NixOS: The Good, the Bad, and the Ugly
(pierrezemb.fr)
From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

But for like 99% of development teams "repeatable" is Good Enough(tm).
So, containers do not get you reproducibility.
For dev environments, repeatable is okay. If you want actually reproducible binaries that you can ship, Nix is better fit for that purpose.
I'm not quite sure why you fetishise a bit-for-bit over semantic equivalence. Doesn't it turn "it works on my machine" into "it works on my machine as long as it has this sha: ... "?
You absolutely do. If you build a container and publish it you will pull down that exact thing every time. How is that not "reproducibility"?
You no what though? Scratch that - who gives a fuck? Bit-for-bit reproducibility takes far more effort than it's worth anyway. Even NixOS isn't completely reproducible. It's a false goal.
It's well more than good enough you mean.
Nobody really needs that.
