Is it useless? 
I noticed, for example, that converting via kindle previewer an epub without this metadata, a warning says no cover is found. |
All three of those things should IMHO be kept, in fact I have thought about the first two before.
As for comments, maybe there are better ways to keep notes about the book, don't abuse the OPF.
Keep an eye on the Modify EPUB thread.
