One of the best features.

Just import everything! Nuget packages, local dlls, other F# script files, you name it. It's so good. No extra ceremony. And when you open it in VS Code with Ionide - you get full support of the language server, documentation and syntax highlighting to know that your script is correct.

Night and day difference with standard scripting languages.

This is where it breaks down a bit.

Importing the same script file twice leads to errors, so you must manually ensure exactly once imports across your dependency tree of scripts.

This is where C/C++ code reaches for include guards, but F# does not have a define pre-processor command (unlike C#).

Fair. I think if this issue takes place - it's probably time to switch from script files to a full .NET project. Or package a distinct piece of functionality as such.

There's no good reason FSI can't be improved to handle this though

If you're interested, you could further raise this on F# discord server or in https://github.com/dotnet/fsharp, F# is effectively a community-managed language so if there's a particular change you'd like to see, there is a high chance you can just make it happen if you have time to see it through.
