I think a big part of the issue with these things is that porting popular applications is not a high priority in the industry. I pitched porting v8 to RISC-V to a few companies a couple years back, and it seems like they were not interested in that. Getting ATX (or other standardized) form-factor boards with chips big enough to test applications on, in my opinion, should be a high priority. As much as people talk about "post-PC" or whatever, PC-form-factor computers are the center of development and understanding, especially for server applications. Being able to buy or use existing power supplies, chassis, disks, NICs, and GPUs (and maybe DIMMs, if that's not a massive engineering challenge) and put together a "PC" I think is really the key to development of the architecture, and they're a portal to applications like Windows laptops (see Qualcomm AArch64 laptops) and Chromebooks (big part of what I was thinking of when I begun and abandoned porting V8). If there were ATX form-factor AArch64 boards available for less than a thousand bucks early on, it would have hit Android and laptops possibly a year or two earlier, with significantly less specific investment from ARM Holdings.
