Here it seems that a non-growable export is still growable as long as
nobody is watching. :) Is this the desired behavior?
Yes, absolutely. “Growable” is documented to mean that writes after the
end of the exported file will grow it to fit. Explicit truncating is
something else, and I believe we should allow it on all writable
exports. (Of course only when other potential users of the block node
in question allow it to be resized, but that’s what the permission is for.)
