> I'm not sure what Apple can do here;

Hire more reviewers. Apple is making a shitload of money from App Store sales (and of course by scamming its users in many creative ways). They'd better spend it on making developers happier, not on thickening the walls of their garden.

They don’t make a shitload off the small apps like the synthesizer from this post. They aren’t going to introduce more expensive Cupertino and Cork reviewers to help that category of dev. They’re a business and will automate instead of have small time earners occupy more time on reviewer desks.
