Agreed. That's one thing that peeved me about that. They'd spent a lot of time convincing people of the rebooted timeline, stating that they wanted to do it this way because they didn't want to be burdened by canon, giving them a new opportunity to explore things in a different way. Yet they didn't take that opportunity to tread new ground; they went straight to one of most popular characters of both TOS and its movies. He already got his story told, time for something new! But no, they couldn't help themselves, the temptation was too much. When you reboot something, show me something new, something that wasn't tried the first time around. For Star Trek, that means showing something that wasn't shown during its original run.
But knowing this, it's not at all surprising what they did with SW.
