That definitely was the case when I attended NTSU from 1971-73. I studied with Roberts, took Piano Pedagogy from Rogers, and later studied with Cass when he moved to UMKC in 1976. This particular issue was never discussed - although Mr. Roberts tried very hard to break me of the bad habit I'd slipped into of sometimes "rolling" chords when playing Brahms......

carey:

Thanks for the backup. And, hey folks, this comes from a guy who used to play the piano at a Shakey's Pizza Parlor!

What he also did was to play the Ricordanza for his successful DMA audition. It was simply beautiful.

You still have much unanswered ground to cover here.

The things we're raising are important and could be good practice for you, because they'll be raised if you succeed in taking your stuff to a larger stage -- and it wouldn't be bad for you to be ready.

Don't you think there is a reason why that "tradition" or trend died out?

Oh my gosh Louis, you have an amazing memory. It's been over 40 years since we attended NTSU and studied with the same teacher. It's a true pleasure to hear from you again !!

This topic was as well brought up on the Adult Beginners Forum and also on the Piano Teachers Forum and the OP collected there the same overall response as here in the Pianist Corner. Those other two threads are dead, which to me means that there is nothing to add to the topic.
As this thread here is still active, but I am afraid to once more see a forum thread on risk to develope into smart-alec discussions ending up in endless terminology and personal misunderstandings, I would like to try to summarize all the story like this: what´s for the OP an exciting insight into alternative musical fashions, as they have always been around, it to others is not much exciting but just a matter of knowing that music can be annotated, interpreted and expressed in different ways. From beginners to teachers to university study pianists comments have been collected which show agreement on the practice to roll chords and disagreement that there would be something amazingly new about it.
So, let us spread the word that different musical fashions existed and exist and that it is not necessary to stylistically stick to only "one truth" on how to make music. Isn´t the story that simple?
