Seems there are not many responses from other people so I'll try to start the discourse.
First, thanks for registering on the forum. Welcome! I think a lot of knowledge is contained here about the app, so looking around is always a good idea.
Second, I understand English might be not the native language for you and I appreciate the effort to make your thoughts known. Yet currently I can't understand a few things with your posts.
I get that you want to combine the plugins and there's some rational behind that but can I ask you please clarify the reasons to do it in one easy to follow list?
Right now, motivation, suggestions and just random comments are in the same blob of text and it's kinda hard to get what's your end game.
Can you illustrate common use cases and advantages over current modular approach?
Do you have implementation in mind?
Would you like to work on it by yourself or is it just an idea for devs to consider?
P.S. just a user here, trying to give a hand another one. Please don't expect much from me.
