I have absolutely done that in the past, and I would do it again in a heartbeat. I can slice off exactly how much I want, getting a good feeling for the portion size. The noodles stick together, there is no unfurling and subsequent mess when transferring them to a dish. They’ll loosen up a bit when heated, but stick together enough to offer a superior eating experience - just cut a piece off and consume.
Same here, I’m a part time spaghetti vandal that breaks spaghetti at least once before throwing it in the pot.
I also use both fork and knife to slice though the spaghetti mountain on the plate!
But I draw the line at overcooking spaghetti, not fond of spaghetti soup.
