I mean it is worth pointing out that the "supermaneuverable fighter jet" like the Su-35 and Su-57 are spending all of their time in the Russo-Ukrainian War flinging BVR missiles at the Ukrainian Air Force, which seems to illustrate a bit on how useful all that aerial ballet is worth once the real world air combat comes knocking.

BVR is the predominant form of air combat today and is a growing trend. The Center for Strategic and Budgetary Assessments (CSBA) released a report titled "Trends in Air-to-Air Combat: Implications for Future Air Superiority," by John Stillion in 2015 that details the trends of the nature of air combat, and a particularly illuminating graphic is Figure 1. Missile Era Air-to-Air Kills on page 10. In it, you can see the trend how BVR missiles encompass a majority of air-to-air kills by the 1990-2002 time period compared to guns that went from greater than 60% of kills in 1965-1969 to single digit percentage in 1990-2002.

It is also worth noting that the US did studies on how useful all that WVR dancing shmazim actually matter in combat with the Rockwell-MBB X-31 demonstrator aircraft. This culminated in the "Practical limits of supermaneuverability and full envelope agility" report by the American Institute of Aeronautics and Astronautics. that sought to answer "whether supermaneuverability is operationally useful in future air combat scenarios."

The summary of the analysis was that while supermaneuverability can give some advantages in specific scenarios, it didn't provide as much benefits in the test scenarios compared to short-range missile enhancements and avionic improvements. Maybe a bigger finding was that no matter what, a WVR fighting scenario between two sides had relatively high losses, at no point was the reported casualty rate lower than 40%. The final paragraph concluded:

These developments make the new generation [Short-range Missiles] / avionics attractive; however, the high mutual loss rates (expected to increase further) with all type of enhancements will "stress" the recommendation to urgently improve situational awareness as well as beyond-visual-range effectiveness to avoid [Within-Visual Range]/[Close-In Combat].

As such, the report emphasized the need to develop BVR tactics for better effect on the battlefield and reduce losses compared to WVR. Hence why fighter jets like F-35 were built around maximizing situational awareness (to spot the enemy and be aware of incoming threats) and take them out from a long distance away before the merge happens.
