CMV: Greenify is still required in Oreo. Doze, App Standby & limiting Background Activity cannot substitute hibernation

I have read several times that "Greenify is no longer required after Marshmallow because of Doze". I disagree.

Disclaimer: I've no app-writing knowledge, just a long-time Android user with 300+ apps on a rooted Nexus 6P. I did some research to form the opinion below. Feel free to point out my misconceptions!

Doze can only save battery during screen-off time, by disabling network access, denying wakelock and JobScheduler until predefined "maintenance window". ForceDoze merely shorten the time between screen-off and Doze. It doesn't help when my screen is on. All apps become "active" when I exit Doze, and the phone may become slow when I switch on the screen.

App Standby can "doze" apps during screen-on time, but it only applies to apps that are inactive for some time. (I cannot find how long it takes to become inactive) All apps become "active" when charging, and phone may slow down the moment I start charging.

The Background Activity switch in Oreo can help enforce older apps to conform with Oreo Background limitation - by blocking implicit broadcasts, force the use of JobScheduler, etc. There will be less wakeups by the apps. I'm not sure, but I think it just make outdated apps to be more controllable by Doze.

The problem is, I need to use some poorly-written but irreplacbale apps (e.g. local govt apps, local news, transportation, food delivery or heavy-ad apps) These apps may have a background service to receive notifications (which I don't need), or may update content by itself, etc. Only Greenify can help me keep these bad apps in check, by making sure the app won't restart regardless of screen on/off and broadcasts. It's important because I use my phone all the time when I'm travelling or working outside.

If you only use a selected few and well-written apps, Greenify probably has no use. If you use many apps like me, without Greenify, I have a feeling that those bad apps will eat battery and slow my phone down badly. Let me know if I'm wrong!

Removable batteries discussion

I have always preferred phones with removable batteries so far, thinking that it will most certainly be the first component in a device to fail. I have even advised people in my circles to do so, until a recent event. A family member of mine still uses a HTC DesireX. Recently, he wanted to replace his battery because of swelling. He bought two matching batteries from different sellers. The problem is, even though they were unopened/sealed packages of original batteries, they were not holding much charge. (I suppose they waited on a shelf for some time.) This made me question myself. In the past, I have used nokia smartphones, and they were easy to replace with fresh batteries, since almost all nokias used the same battery type. Now with android, its all over the place. Is it even worth it to go for a removable battery device when you cant find a replacement a couple of years after you purchase it? What do you think/prefer? PS. I realize this is not exactly fault of android OS, but ...
