-Subject: [PATCH] Disable source build by default, and opt in instead (#8019)
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-* Add sln filter for source build
-
-* Use ExcludeSourceBuild instead
-
-* Put the correct default in 🤦‍♂️
-
-* Don't include npm targets when all targets are suppressed
-
-* Don't override arcade for test projects when building from source
-
-* Use default source build jobs now we don't need node
-
