Why is endgame just treat as a minute ot so for the survivors do escape

Let's be real, what can a killed do in endgame? Maybe secure one kill Vs a group of solo q survivors? I wish killers could defend gates more, maybe have them regress naturally and have the ability to kick them and regress them more, the ability to close a gate when it's opened (not completely reseting progress to 0 obviously) just something for the killer to do in endgame to keep them engaged and not encouraging them to grab a survivor and camp them
