Or Crisis happens, and Supergirl dies, and Brainy freaks out that she's dead, despite the fact that he has a time machine. She didn't 'just' die. She's been dead for 1000 years. Brainy and the Legion can continue having adventures with the Kara from a year, a month, a day before she died, *for the rest of their lives*, sending her back to meet her eventual fate each time. It's not like it's 'taking time' out of her busy life, since they've always been able to send Superboy back to the exact second he left from, so that he can not miss school the next day despite spending a week adventuring with his future pals. They could have done the same with Kara, just not bothered to tell her that, *like everyone*, she's going to die eventually. But they have her entire pre-Crisis life to access (and if the nonsense about her retroactively never existing was actually a thing, Brainy would never have remembered dating her in the first place, and the entire Crisis would have never happened in the first place, which makes the entire notion of 'retroactively didn't happen' a bit silly).
There was cake. They could have cake (Supergirl still active in the 30th century) and eat cake (killing her off in Crisis) at the same time, thanks to time travel, but they seemed to fail to understand how it works, and decided that since she'd died in 1985, that people who lived in 2985 suddenly couldn't go back to 1984 anymore...
Hypertime, on the other hand, from the Superboy series (IIRC) was pretty awesome. I love alternate takes on characters, or alternate universes, like the Age of Apocalypse over at Marvel, or the Earth 3 Crime Syndicate, here at DC, so hypertime was right on target for me!
