I don't see a problem with that at all.  If you don't want things to break
because you're requiring servers, then don't use the "required" checkbox.
 But I can see value in having the option of specifying that you'd rather
have uploads fail if your desired set of servers isn't available.

Assuming this functionality can be exposed via the API, you could always
build an upload tool that allows you to implement whatever sort of selection
criteria you want.  I think the simple binary selection is the right way to
start.

So don't check "required".  Instead, uncheck "allowed" on all but the six
servers.  Or if there are only six in the grid, just leave it alone and the
defaults will do what you want.
