My thoughts on the 3 hurdles:
Agreed, the biggest hurdle is the interoperability. Reliable VMS Direct driver support will be a long time coming. ONVIF taking their time, writing more Access Control Profiles before h.265 extensions etc.
Reasonably priced video cards (~$100) with HEVC hardware decoding are starting to appear. When supported by the client software, this should narrow the performance gap significantly.
But as you allude, h.265+ is the option to compare, and it is looking pretty good. The last Wisestream 265 vs 264 1080p comparison was showing 40% reduction.
Maybe not that rare.
Although, true VMS interoperability approaching h.264 levels will take a couple of years or more, there are an enourmous number of kit product sold today from Dahua/Hik and Hanwha, not to mention the Longse's of the world with h.265.
These propreitery implementations sidestep the driver issue, and should lead to widespread usage in matched camera/recorder systems in 2017.
How big is the Dahua/Hik/Samsung/Longse kit market compared to all sales, in terms of overall units? Dunno.

Yeah I agree to certain extent most of the H265 codecs or more specifically H265 software decoding, is really iffy right now. although I will say if video cards/processors get cheaper and the software decoding get ironed out in a year I could see it being a thing.
then again aside from the low end market even some of higher end are starting to push H265 like Panasonic new extreme series that are going to come out Q1 next year supposedly. Doubt Panasonic will start a H265 trend in the higher end markets though....

Update: added section on H.265 hardware decoding in latest XProtect client.
H.265 Hardware Decoding In XProtect
The latest version of Milestone's XProtect Smart Client supports hardware-accelerated decoding of H.265 video streams (for the versions of XProtect that support H.265), on QuickSync compatible Intel processors. According to Milestone, H.265 decoding in hardware still takes a greater toll than H.264 decoding, but it does allow for ~3-5x as many streams to be handled vs. doing decoding in software alone.
