Nicely put.  Now we've just got to convince dono that an object *does*
'physically' have a shorter spatial length (ie take up less physical space;

I had a hunch that you will not get this. This is what happens when
you are more interested in being always right instead of getting it
right <shrug>

Let's put it this way. Length is a result obtained through a
prescription, one that typically involves recording two spatial
locations simulataneously. Length is a physical property. However,
because simultaneity is frame-dependent, the physical property length
is also frame-dependent. There is, however, no physical process or
interaction occurring to or in the rod to change its length.
