I`ve owned and used many sleeved guns throughout my shooting career,from cheap trade jobs on low end guns to better work on what had been `best` guns when made.Never had one issue with any of them and many were guns that would have been scrapped if not for sleeving!!! It may carry a stigma but overall I feel it is a benefit to those interested in keeping guns working,although it is being carried out much less nowadays as the value of s/sides has and is diminishing.
