yep, PR #1297 has been open for over 3 months now. Looks like it still needs codeowner approval.

People subscribed to this issue: you may be interested to know that powershell has just become an official formula in the homebrew/core tap following merge of Homebrew/homebrew-core#268901. If you want to install it, run brew update, and then brew uninstall powershell followed by brew install powershell. That should pick up the formula from the official homebrew/core tap.

Note that there are no bottles (pre-built binaries) for the powershell formula on Intel macOS due to dotnet@9 build issues (see Homebrew/homebrew-core#197546).
