I do know this, I'm currently putting together a training course on authoring SELinux policy.

Surely the fact that 'disabling SELinux' is the top result on the subject in Google or StackOverflow will tell you that you would be in the minority of developers that like working with it and find it easy to do so.

I think there's more to it than just simply running an app without receiving an AVC complaint in auditd, you need to be able to test that the controls you put in place actually protect the application in some way, this does not come for free with audit2allow and other such generative tools.
