But the proposal is not to remove the _code_. The proposal is just to
remove that "#ifdef" lines that would make it conditionally compilable,
*if* the symbol that they test weren't always enabled. In other words,
turn it from "always compiled, but you can turn it off although nobody
does" into "always compiled".
