I understand why people love Obi Wan, but I also struggle to really see what the point of his stand-alone story is.
We've already seen all the interesting portions of his life, from being a padawan, to a full-fledged Jedi, though the Clone Wars and the fall of the Republic.
Who really wants to see him hang out and do nothing on Tatooine for 18 or so years? That's the only unexplored timeframe of Kenobi's adult life. And while it might be interesting to find out how he went from 40 to 80 in half the time (and no, I'm not serious, that's not actually interesting), what can he possibly do? Trying to shoehorn in Kenobi as Rey's father is a terrible idea. I hope it's not true, but even if it is, it should stay like Luke and Leia's parentage in the prequels. Something we never saw, lol.
Seriously. Some mystery is a good thing. The Clone Wars were ten times cooler when in the original film Obi Wan just said he fought with Anakin Skywalker during them. "What were the Clones? Why was there a war? Wow, that sounds awesome!" The answer? "Well, the Clone Wars wasn't really about the Clones at all. They were just the principle military asset for one side of a civil war, and the fact that they were clones was actually kind of irrelevant to the greater reasoning for why the war happened, nor did they really factor into what happened at the end aside from being used to kill the Jedi. Seems kind of weird to highlight the clones when the result of the war was the dissolution of the Galactic Republic and the installment of the Galactic Empire. In fact, we're not really even sure why Yoda called it The Clone Wars in advance, like he'd already read about it in a history book or something. You know, kinda like how nobody called World War One World War One while it was happening. You'd also think it would have a more descriptive or propagandic name, depending on whose side of it you were on."
In short, to adapt a popular meme: "Leave Obi Wan Aloooone!"
