The good news is that the Append command is not obsolete. It has been listed in the docs as that for years, but it has been rehabilitated. Note that you don't get a warning - that's intentional. Note that we need to move it back in the docs - that's todo. You can do things with this command that you cannot do with the function - actually the function is not all that useful.

The bad news is that, I put my foot down and said "Either the Append command goes or I go". With five pages of Append command defense, the choice is obvious.
