It doesn't solve it, because it is confined to a relatively niche GNU/Linux distribution, unlike Docker.
Also, even if you come up with a forward facing solution and demonstrate it only on a particular domain you still, IMO, deserve most of the credit for solving the problem even if it takes others to translate it straightforwardly to other domains.
I'm less sure about windows, can you explain a bit more how you use docker containers for providing "native" windows stuff (as opposed to as a more lightweight linux VM replacement when developing something that you really want to deploy on linux)?
Usually the traditional option would be to snapshot the VM right after the first successful install.
However stuff like Windows Nano now makes it interesting to start playing with containers on Windows.
That is definitely an exaggeration, considering the utility the industry leverages with plain Dockerfile's.
However, I am curious about the specifics that you are probably thinking of, if you'll elaborate.
I know some people write Windows software from Nix, but this is a way for Linux developers to make desktop apps for Windows users, not a solution to any problem Windows developers have.
1. They want to create a Game or Windows end user UI App (e.g. Overwatch or Photoshop)
2. They write some internal corp tooling or B2B software for windows shops (e.g. gluing some SAP or Oracle garbage together)
3. They want to write a server application (which means deploying on linux, which is basically the only server OS left). But they do not want to run linux as their desktop OS for corp or private reasons.
The 1st category probably has limited use for either docker or nix (in the absence of first class windows support). Might still be useful for tooling though.
The second category probably has use for docker mostly as a shitty linker, maybe also for isolation/security (I don't know the windows docker ecosystem).
The 3rd category can and totally should be using nix and I'd guess is at least double digit market share (so not insignificant; e.g. before Google banned them, a large fraction of Googlers had windows notebooks).
I don't use Windows as pretty UNIX, rather for its own capabilities.
