It would be a garbage fire in any language
Python is installed on most systems and easy to install when it's not. Only Azure is dumb enough to bundle it, and that was a complaint in the bug - there's no good reason to do so in this day and age.
The performance bottle neck in all three is usually the network communication - have you seen cases where the Python CLI app itself was using 100% of a CPU and slowing things down? I personally haven't.
Looking at the crazy way Azure packaged their CLI, it's hard to believe they weren't making it bloated on purpose.
Not on Windows.
And which Python are you talking about? I mean, Python3 is forward compatible but you SoL if you have the bad luck of having an older interpreter installed and you want to run a script which uses a new construct.
Also, AWS is 10 years older than Rust, and C# only runs on Windows (at least it certainly only did when AWS was created, and is laughably more difficult to get running on Linux or OSX than Python).
You're funny

$(dotnet publish) <https://learn.microsoft.com/en-us/dotnet/core/deploying/sing...> is the way they solve that problem in modern .net
And, unlike the scripting language you mentioned, most of the languages on the CLR actually are statically typed
That may work now, but it didn't exist when AWS was started.
