Yeah I'm not too worried about what's on the deployment end, but rather the dev environment. I don't want to spend any time wrestling Docker to get it to function smoothly on non-Linux operating systems.
Agree that it's a strong argument for using newer languages with good tooling and dependency management.
the dev workflow usage of docker is less about developing your own app locally and more about being able to mindlessly spin up dependencies - a seeded/sample copy of your prod database for testing, a Consul instance, the latest version of another team's app, etc.
You can just bind the dependencies that are running in Docker to local ports and run your app locally against them without having to docker build the app you're actually working on.
I've run Docker devenvs on Linux, Windows (via WSL2 so also Linux but only kinda) and Mac.
The closest I've come in years to having to really wrestle with it was the URL hacking needed to find the latest version willing to run on my 10-year-old MBP that I expect to run badly on anything newer than 10.13 - the installer was there on the website, just not linked I guess because they don't want the support requests. Once I actually found and installed it, it's been fine, except that it still prompts me to update and (like every Docker Desktop install) bugs me excessively for NPS scores.
