rack n pinion front steer ackerman issues...explain...

A LOT of it comes from people simply trying to throw around terms to make themselves sound more intelligent than they are.

Aside from that, the need for Ackerman geometry is imperative to prevent tires from slipping around turns.

Pretty simplistic explanation to get everyone on the same page in case you don't know what Ackerman geometry is.

Since the wheels track different diameters in a turn, it's necessary to allow one wheel to turn at a different angle than the other to avoid wheel slip. It's all in the article above and very easy to understand.

Why people make a big deal about is probably because of the reason I stated. There's nothing setting steering up correctly.
