I'd rather not have this, and I'm saying this as a commander main.
A bigger headache than not having observers is observers who don't actually do their job and stick with you/don't maintain proximity/run off and ignore you when you need to call in support.
Adding in extra guns exclusive to the Observer class just attracts more people who clutter up the class and act as a liability rather than playing to their role. Such people are a triple liability, since they; don't do their own job, prevent others from doing the job and prevent the commander from doing his own job.
More often than not, I can get observers by asking; a much bigger headache are people who fill up the observer role, play like a rifleman (ignoring the commander) and thus prevent people who are actually going to be useful from taking the role (something that the proposed change would greatly exacerbate by attracting more of this kind of player).
