Oh I am going to love this conversation but I will start by not reading any of it to get my initial impression and then I will edit it after what I see.

FRC has always had this certain game "feel". To be honest the only components that I feel are required for that "feel" I get from standing behind students and yelling are auton, and tele op. I participated in FLL if you haven't done that when competing you take your robot to the field put it down and press start. BEST never had the robot to robot to interaction. FIRST has done a great job with having an exciting game to view between the size of these robots, robot to robot interaction, and robot to environment action it feels exciting. That being said you don't need to have an end game to still provide that same feel.
Outside of that End Games do provide additional engineering challenges which is great for STEM. It "GENERALLY" will provide for more depth in strategy. Anyway time to read the posts and realize how ignorant I was...

EDIT: After viewing what everyone has said I still am standing by the fact that you don't need an END Game for a good match. Seeing something mechanically similar to an endgame a window of opportunity or a window to score in a different way that is high risk high reward. I always thought it was a shame that the hot goals were used in one portion of the game, why not make it so the Hot goals were toggled on randomly throughout the match and bonus points added then. I will admit that when I started the END game was the equalizer. If you don't have the sharpest auton you could make it up with a good end game.
Anyway my proposal to the GDC you know as some random dude on the internet with all the mad street cred that comes from it. Design instead of an End game include in the matches periods that slightly deviate from a task in a high risk high reward manner. Make the hot goals random during tele op (balanced of course.) Signal mini bots to climb at any point in a match to make shot calling more dynamic. Challenge teams to instead of designing for such a routine system of Auton->Tele Op->End add a wild card to Tele Op lets mix it up.
