Yes, I expect
Amazon to keep improving things. They're good at constant improvement.
In many instances when streaming stopped, an error message popped up and asked whether to send an error report -- I must've sent about a dozen over the course of watching Downton Abbey's second season. I'm guessing someone will be looking at the mass of error reports from users, and for tweaking to happen.
I've also been a longtime user of Audible. That service improved dramatically, after
Amazon bought it. It seemed like the big difference was fewer server crashes and now there's no streaming as slow as molasses from their end.
Amazon has money and smarts, and a good track record. As a customer, though, I'm in it for myself, and if there's better service from one vendor vs. another, I don't cut slack for intentions -- I look for results.
