I don't think it's an issue that is worrisome with a large transmitting loop.

The useful property of small loops is that they have a very clean
pattern with very deep nulls.

Any loop response to common mode currents on the feedline will ruin
the pattern.  Preserving the balance of the loop with respect to
ground helps common mode rejection, and helps preserve the nulls.
