To prevent back yard mechanics from defeating the limits and causing harm to other motorists and liabilities that would ensue. Way cheaper than lawsuits.
Wouldn't different steering knuckles, with an added boss that contacts, say, a point on the wishbone, be cheaper than an altogether different steering rack? Maybe the different steering rack has a higher performance aspect to it... and is not related to turning circle / steering rack travel limits.
