Summary of the new feature

I was looking at the build.ps1, and I noticed that we now have a few checks for folders (PSES and Snippets), but no way to "clean" the environment. Before working on a bunch of scripts for this, I thought I would put it out there to consider different options and decide upon one? My preference would be to consider Invoke-Build that is used by vscode-powershell, but that's only because I have experience with it. Are there other build methods that we could use?

Is it worthwhile to continue creating our own build scripts to reduce dependencies?
