What
Command safety analysis on Windows now recognises more PowerShell cmdlets, including location and output ones (set-location, push-location, pop-location, write-output, write-host), pipeline and formatting ones such as where-object and format-table, and a download-capable set flagged as dangerous (invoke-webrequest, iwr, new-object, start-bitstransfer). The shell binaries pwsh and powershell are named as a set.
Evidence
start-bitstransfer
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
