Strictly speaking adding this is a compatibility break, given that previously % weren't special. But I'd argue that was simply a bug, as for the much more prominent Environment= service setting we always resolved specifiers, and DEfaultEnvironment= is explicitly listed as being the default for that. Hence, let's fix that. Replaces: #16787
System and Service Manager
