While I agree with everything you've said, I also wonder if some of it comes down to how hard it is (in my perception, at least) to get access to it? With almost all other developer-facing technologies, you can get a sandbox environment set up, a free tier subscription going, etc., within a couple of days or so if not a few hours. With the exception of SIP, I have no idea how I'd learn or demo any of the things you mentioned as a random developer. Even if my company asked me to. My immediate assumption would be that you need to be a fellow telco or a multi-million dollar customer to get any kind of access to this stuff. And that setting up a lab of your own to play around with requires pouring though thousands of pages of obtuse standards and documentation to make any sense of it, not to mention the radio hardware if you want to actually interface with modems? It's a shame, because telecom seems very cool, but I just have no idea where you'd even start.
