What module lifecycle hooks are available in V8, and how do they compare to V7’s logic hooks?
If I am not wrong, you can use all the below logic hook parameters with the v8.
What do you mean by “module lifecycle hooks”?
Will the use of the v7 logic hooks still be upgrade safe going forward?
Since we create all of these logic hook in the custom/ folder.
Yes, they will be upgrade-safe. 
Not all v7 logic hooks will work in v8, some just don’t apply. Most of them work, though.
Off the top of my head: no longer there in v8 (except perhaps for legacy modules, but that is also going away soon):
after_ui_frame, after_ui_footer
after_login, before_logout, after_logout
Thanks for that, I encountered that exact same thing. So confirmed!
The hooks were very useful TBH - but progress I do suppose
