I have done this with three factory barrels. My reason for doing it- after barrel break in I worked up some test loads and the barrels showed promise. Further load development got me pretty happy and I decided the barrels were worth more than just inexpensive range practice while waiting for my other barrels to cool between strings...they were pretty good shooters. So I had them threaded for suppressors.
Had the barrels been trash, I probably would have been more frustrated with the poor accuracy and grouping, and would have replaced them as soon as funds became available to do so, and I would not have bothered to thread them. Because they grouped well and were consistent, I knew I would keep them and would want to suppress to extend the enjoyment on longer range sessions and any hunting trip that they would be well suited for.
All of that is a long way to say- if you plan to keep the barrel and put more than a box of ammo or two a year through it, and if you already have a suitable suppressor that could be used on it, I would have it threaded.
