I actually had a chance to do that once:

I was very careful to space the antennas exactly 300mm apart, but that
didn't inspire them to align in any way.

In all fairness, those were "timing" receivers so nobody cared where
their phase-center was during production...

Never attribute to malice what can adequately be explained by incompetence.
