It feels like the Photos app continues to become more cluttered with features that everyday users really don’t even use in every major iteration of iOS. At least for me, I find myself really only ever using the Albums view in the Photos app to get to my most important stuff. I don’t ever really utilize the People or Places albums, nor do I ever use the Memories or Shared tabs.
For anyone who feels like they're in a similar boat and miss the simplicity of the Photos app as a simple album-based Photo Library viewer, a new free jailbreak tweak called Photo Tools by Justin Petkovic might be able to give you exactly what you’re looking for.
