There is indeed the phenix.cut_out_density tool (by Tom Terwilliger)
which does a nice job of reducing the size of the output mtz-file (it
shifts the cutout region to the origin and reduces the unit cell).
On the link-versus-attachment issue, certainly the link is preferred,
but the aforementioned tool produced in my tests the mtz-file as small
as 50kb, which is not too bad.
