Not really going to take off until they release Ryzen APU's. Just makes more sense to get
I really doubt that. There a lot of people (including myself) that have been switching over to ITX systems over the last few years for multiple reasons. Gaming, portable Work station, small foot-print case on the desk, Ect. (There a reason there been an explosion of gaming capable ITX cases since 2014 on the market).
If you start browsing around the web, you find plenty of people that have been asking for these ITX board before the launch of the R7 cpu's.
Now of course, the HTPC market is still a big area for the ITX board (where APU's make sense) but the other market segments for ITX boards have become fairly large and would benefit from having these more powerful R7/5 Cpu's.

The lack of onboard graphics on Ryzen chips makes it strange that they bothered to produce these, with no current product that can use the onboard video outputs. Unless the new ZEN based APUs are a lot closer than we've been lead to believe, wouldn't it have made more sense to release boards without video ports and more USB or something else useful? Or perhaps just a reduced price?
Eh... You could make a few arguments for both sides, having video ports and no video ports.
You could have it just like you said, without them, you could have more useful ports or a cheaper price for the lack of ports (because of lack of products to use the video ports).
For other people, they could view it as the ability to swap hardware to fit your changing needs (maybe you want a lower power bill and dont use the power of your gpu/cpu anymore) or giving someone a part of your system as your upgrading said part.
(could be the motherboard where you needed some features that your current one lacks but you'll still be using the same GPU and CPU. That new owner of your old motherboard can just a slap an APU in it to get it up and running.)
So you could view it a long term flexibility for the reason why they're on there. Or could just view the motherboard markers as crazy fools that dont know what processors are currently on the market. lol.
