Do you believe it is still worth participating in the preview for developers after receiving current phone updates? I participated before in the past few months, then I decided to set the phone aside November of 2014 which I remember receiving cyan for the Lumia 521. Now I decided to pick the phone back up again as my secondary phone. Got it all set up, but still not certain if the preview for developers would benefit the 521; any input is greatly appreciated.

With WP10 preview in the immediate horizon this is exactly the time u need to be in preview :)

It depends what you mean with secondary device. If you use it only if your main phone is out of order or if you are going to do something which may damage your phone like mountain biking, P4D is not really needed. Because you only need it make a call.
But if you use your second hand phone to "experiment" than P4D is a nice tool.

Nice, that is something to look forward to; Thanks for that. I am going to go ahead and redo the preview for developers again, good looking out.
