Exactly my situation. I want to delete "Photos" with a passion; I load many cards a day from my video cameras (4) and Photos wastes many minutes a day. Grrr.
Is there any safe way of nuking this crapware?
Depends on the definition of "safe".
You can remove Photos by first disabling SIP in Recovery mode and then using instructions in my post #16. When you are done you should enable SIP again. Removing Photos probably wont cause no ill effects but obliviously you do so at your own risk...
I suspect that later OS update will simply install Photos again so you might want to wait until last El Capitan update ( probably 10.11.5 or .6) before removing Photos if you don't want remove it after every update.
