A different answer to "What does Scuderia Ferrari (SF) mean?"

There have been many threads that answer the question "What does 'Scuderia Ferrari' mean?" Like this one, and this one, and this one, and this one, and this one. It, of course, refers to the racing team; but most translate it to mean literally "Ferrari Stables" and loosely "Team Ferrari".

In this nice web article on the Enzo, they gave the following explanation that actually seems far more insightful:

Scuderia Ferrari - This is the name of Ferrari's racing division, and was the name of the original racing club Enzo Ferrari formed in 1929. "Scuderia" comes from scudo, which means shield. In Italy's past, armored knights would fight in competitions, represented by a shield (or coat of arms) from a certain region or town. These regional teams came to be known as scuderia.

Can anyone confirm or deny that? That's the best sounding answer I've heard. However, the closest I've found to confirmation is Strasse's answer in this post.

 

But where does the use of "scuderia" to mean "stable/team" come from? Perhaps from the explanation above... in the days of knights, "scuderia" was used to mean a team that fought under a particular "scudo" / shield. Thus, the Ferrari use of it was in the traditional sporting sense, rather than something derived from its cavallino mascot.

Good point; that somewhat further justifies that it has nothing to do with "stables/horses"; but rather, the traditional sense of a team fighting under a shield, born in the days of knights.
