No, it isn't, provided it's a solenoidal coil of reasonable length. I
don't think anyone disagrees with this. The disagreements are to why,
and what would happen to the current if the coil were made very short.

The phase shift measurements are being made using a signal with
unchanging phase and thus incapable of providing a phase shift.

The disagreement is what would valid phase measurements actually
look like if a signal capable of changing phase was used to make the
phase measurements.
