If you gave every author "admin" rights ("admin" means being able to set
or change ACLs) by acl_rights_default, he could change ACLs on pages not
already having ACLs disallowing that change.
But be aware that this is a bit dangerous. If you give that right to an
idiot, he can put new pages on the wiki (or change unprotected pages),
so that they can't be changed/reverted/deleted by other people except
the wiki admin himself.

There is no ACL inheritance yet.
Even the pages you see as "sub"pages are on the same level in reality
(see data/text/ content).
So, except that's what set in moin_config, you have to set ACLs on every
page individually (if needed).
Can be done, but also easily forgotten maybe.

This is not possible. Maybe some day we have ACL inheritance, but not in
1.2 and not in early 1.3, definitely.

There is not really a wiki admin in moin. It is just usually called like
that, when you make some specific user have admin rights (and all
others) by moin_config.
Make an AdminGroup page (== contains people having admin right)
acl_rights_default = "AdminGroup:+admin Known:read,write All:read"
acl_rights_before = "BryanDerksen:admin,read,write,delete,revert"
If there are usually no secret pages, use this additionally:
acl_rights_after = "All:read"
So you don't need to specify it on pages having ACLs. If you want to
make a page secret, you still can write "#acl .... All:" onto it.
If a new trustworthy author JoeDoe joins, put him onto AdminGroup and
tell him to put that onto page JoeDoe and subpages (and all other stuff
"owned" by him):
Except BryanDerksen, nobody will be able to change those ACLs or do more
on the page than "read".
Please test that, I didn't try it out. :)

If a page has no ACL on it, AdminGroup people will be able to do bad
things. So at least on FrontPage, RecentChanges and other important
pages, I would put some page ACLs...

If JoeDoe makes a new page, he will not get admin rights this way. ACL
processing stops on first hit, except +- is used.

"default" applies to any page not having ACLs defined on it.
"before" and "after" are just processed before/after the page or default
acls are processed.

I am not totally sure, but I think this is not true.
If you succeed, make a usage case on MoinMaster:HelpOnAccessControlLists
