I think the point of this was to avoid problems by using keys in object with names like delete (looking at the commit where the file was changed to emit this error will probably have more info). Depending on that, we could avoid it on the expression if it's prefixed by an object.
It's still a warning, so it doesn't break the app.
The workaround is using $http['delete'], which is quite verbose

For anybody willing to give this a try: I marked this as a good first issue but it might be harder than I think because it depends on the logic that exists regarding the warning

because you can't use delete keyword as variable name.. these are reserve keywords but if you still want to use it then try brackets like this : ['delete'] : value
