Default Shunt vs. Series Feed

Hello,

The question I have pertains to feeding an MW AM broadcast antenna tower
but also applies in the ham arena as well. Given the advantages of
shunt over series feed (no base insulator, tower grounded (lightning
protection), no lighting chokes/ring transformers required, etc) why has
shunt-feeding of AM broadcast towers been used to-date in relatively few
instances in the U.S.? The argument that the slant wire to the tower
adversely modifies the antenna pattern doesn't seem to hold up in theory
or practice. Thanks for your time and comment and 73s from N4GGO,
