It would be hard to wear the slide release out anyway. Since either school of thought works use the one that works for you. Some semi-autos do have an issue with shifting point of bullet strike on target depending on method of of release by sling shotting the slide to release it or hitting the lever or button. Not all pistols do this nor are the gun gurus all on the same page with this issue. Some people have trouble reaching the slide release without changing their handgrip. This can cause a time consuming hand regrip or bobble when time counts. So some just resort to sling shooting the slide and be done with it.
