Classic campfire perspective, you seem to have no actual experience with the issue in question but disparage it while at the same time making a wildly inaccurate statement about another thing: “questionable steel quality”. Get real.
I'm a machinist and work with different kinds of steel all day, so I know exactly what questionable steel is. Care to tell me what kind of "Chromoly" that Savage makes their barrels out of? Because I can tell you it cuts like butter. And why would someone spend between 3-400 dollars on a rebore when a new barrel from a custom maker cost just as much?
It’s $225-$250 for a rebore and now the rifle shoots another caliber.
Spend $300-400 for a new barrel and you have a barrel. You need to send even more now to have a gunsmith install the new barrel.
Some folks don’t have the spare cash to have a custom rifle built whenever they want to try a new caliber.
