Minor variance on #1, I've come to use Deno typescripts for anything more complex than what can be easily done in bash or powershell. While I recognize that pwsh can do a LOT in the box, I absolutely hate the ergonomics and a lot of the interactions are awkward for people not used to it, while IMO more developers will be more closely aligned to TypeScript/JavaScript.

Not to mention, Deno can run TS directly and can reference repository/http modules directly without a separate install step, which is useful for shell scripting beyond what pwsh can do. ex: pulling a dbms client and interacting directly for testing, setup or configuration.

For the above reasons, I'll also use Deno for e2e testing over other languages that may be used for the actual project/library/app.
