I wouldn't do it this way -- it was the hidden nature of the original
support for setting no linked map which led to it being broken (also,
no unit tests -- the combination of a non-obvious reuse of an existing
widget + no unit tests is basically asking for something to break).

I'd suggest instead adding an explicit checkbox here for "always show
all layers for server requests" (but better wording!), under a new
"server settings" group. And a unit test ;)
