Thanks for updating this, @ntotten . The Salesforce release notes will say that the standard template becomes the default (in Salesforce CLI and Salesforce Extensions for VS Code) at R2. I think we should wait until then to merge this PR. We have docs and Trailhead content that refer to the old project structure, and they'll be wrong if we merge this now. Cc: @lcampos

Edit: We do want to make --template standard the default now in the pre-release version of the CLI, though.

I don't want to wait in VS Code. This isn't going to break documentation or tutorials because the commands don't change, the only difference is that the template will have more stuff in it. The reason we are waiting in CLI is that the change of the default template is breaking and we only introduce breaking changes in the CLI at R2. This is not considered a breaking change in VS Code.

Let's update the release notes to reflect that the change is only the default in CLI at R2.

Here are a couple of Trailhead units that will be wrong if we merge this:

• https://trailhead.salesforce.com/content/learn/projects/find-and-fix-bugs-with-apex-replay-debugger/apex-replay-debugger-set-up-debugger
• https://trailhead.salesforce.com/content/learn/projects/quickstart-vscode-salesforce/use-vscode-for-salesforce

There might be others. Those are just the ones I know about off the top of my head.
