It already went. I sent Thi the update (off list), as he requested.

Be specific. "Too many" begs explanation.

Juanma replied to these questions. Each can be useful in come contexts. None
should be mandated for users, of course.

I'd add that change when Emacs is idle can be useful to help you see where
the cursor is. Idle Emacs can mean your attention is not currently at point.
(This change is only from bar cursor to box.)

Which? All?

I have the options on, myself, so I have nothing against having them on by
default. Users of my library oneonone.el also have similar options on by
default. 

As mentioned in the Commentary, some of this is based on ideas from others
(Juri, in particular), and there are some other libraries that do something
similar. That is an indication that it can be useful. And Juanma mentions
that CUA has something similar, which also indicates that this can be
useful.

Wrt overlap with CUA:

I don't know when this was added to CUA; I wasn't aware of that when I wrote
this, which was in November 2005.

If a merge or refactoring with CUA code is in order, then I would think it
would be for CUA to use the code from a separate library, as opposed to
making users who want only the cursor changes use cua-mode.
