Side note that I also created https://linear.app/a8c/issue/AINFRA-841 to at some point integrate PSScriptAnalyzer to lint PS1 scripts.

Not sure that linter would be able to detect missing calls to If ($LastExitCode -ne 0) { Exit $LastExitCode } after each command potentially failing, but would still be useful to have anyway.
