My PG and (after a tuner change) SE HBII Piezo have locking tuners. I really like the convenience. I had a Core HBII Piezo with locking tuners, but I was intrigued by the greater tonal variety of the McCarty 594 HB II, pickup splits and volume knobs for each pickup. So I found a local one last Fall, made in 2023. It has the white plastic, almost shield-shaped buttons on vintage tuners that I think started on this model in 2022(?). I was somewhat wary about losing the locking tuners and thought I could change them if I wanted. At the same time, I actually find the white plastic buttons very visually appealing. I have had no issues with the lack of locking tuners after I learned the trick* of just pulling the string back for one fret's worth, bending the string at the tuner, and tightening the string with the wraps below the tuner hole. Very stable and only a little bit more effort than the locking tuners.
Surprised no one has posted this, the PRS explanation of the new buttons:
"For 2024, PRS Guitars is updating the tuning machines on many of our Core guitars. While, aesthetically, our new Wing buttons are designed to echo the 12th fret bird wingspan design, they were first and foremost designed for tonal reasons all the way back in 1982. Because these buttons are lighter weight than their metal predecessors, they are subtracting less energy from the vibrating strings, thus helping the guitar ring longer and at a more musical note."
