"May" is the most correct word though, it's not guaranteed and VS Code (core) doesn't actually know if things will execute or not as a result of this due to extensions also depending on the feature. Running the "Manage Workspace Trust" command which is mentioned in the [docs being linked][0] to goes into more detail about what exactly is blocked, but we determined this is probably too much information and instead tried to distill it to simplify the decision. That single short sentence is essentially what workspace trust protects you from.

My hope has always been, but I know there are plenty of people that don't do this, is to think "huh, that sounds scary, maybe I should not trust it or understand more", not blinding say they trust.
