Here in 2024, now that my kids have graduated college, in hindsight I'd say both in person reviews and analysis of play along with video review of the same would be very beneficial to a goalie who is really interested in learning the position.
However, in my son's entire goalie career, and that was mostly at AA/AAA levels, not once did a goalie coach ever do an in-game review of his play. There is so many more nuances to the position than just the drills you do with a goalie coach. Don't get me wrong, those drills help by getting the technique down, but I'd think first hand analysis would be the best thing.
The ability to discuss specific scenarios with a goalie based on their real in game performance in my mind would really help goalies who are aspiring to be the best.
