Take a look at the DevOps job postings of lately, tell me that what employers wants you to do is not exactly the same as you did 10 years ago as a sysadmin..
I don't disagree with you but I'd point out that the creation of DevOps was based on the idea that the bridge between Sysadmins and Developers was too large. So why don't we train up some developers on Sysadmin skills?
At least at my company, with two exceptions, if you want to be part of the DevOps team you need to pass a developer interview first.
