Thanks for all your hard work on this over the years!

Something I've wondered for awhile: what are the benefits of continuing Resque development, rather than focusing on making the migration path to Sidekiq as painless as possible? Put another way, what do you hear from users of Resque (like Shopify, as you mentioned in another comment) as the reason that they don't want to migrate off of it?

I was curious about this way back in 2012 when you announced work on Resque 2.0, and I had already made the switch to Sidekiq. I thought there must be a good reason to keep working on it, but I wasn't sure what it was, and I'm still not sure, so I figured I'd just ask.
