I imagine the iMac Pro will be a great machine for a lot of video/animation professionals, and at least some developers, even though I'm not sure I'd call this a "love letter" to them. It's a very powerful machine with an amazing display that takes up very little space. And, yeah, I do think Apple has in recent years been seriously underestimating the value of internal expandability, but I also think critics may overestimate that value to some degree. A lot of people really do buy whole new computers every four to six years; I'm not convinced "but this one is a really expensive computer!" is a definitive rebuttal in the iMac Pro's case. It seems like it'd be pretty easy to put together an iMac Pro that's going to last you past that six-year limit--and, let's face it, if you're in the market for a computer that could easily top $7K in a midrange configuration, you're probably at an income level where doing that again in six or seven years isn't going to kill you. And, of course: we have yet to see what the 2018 Mac Pro is going to be like; the signs are that it's going to be closer to what people who don't like the closed box of the iMac would want. (My biggest kvetch about the iMac Pro is that it seems kind of petty not to have user upgradeable RAM. Maybe there's a design reason for that, but it just feels like awfully low-hanging fruit, given that the "non-pro" 27" iMacs allow this.)
