Dear Orange,
I support your last paragraph.
It’s really hard to guess at what Rav Aaron would say today, because the growth we experienced, was unthinkable sixty years ago.
Eight to twelve blatt a year is not a Lakewood invention. Rav Aaron insisted on two blatt a week in depth for just second seder.
Rav Aaron was not there for the future poskim, or even the future leaders. He was only interested in Torah for the sake of Torah.
