It seems many files still have leading * in their defcustoms. For
example, have a peek at the nxml directory.
BTW, I am curious about the leading *, what does it do? Why so many old
packages are using it?
Would it be a good idea to clarify this in (info "(elisp)Programming
Tips") and also in NEWS?

It was used to mark a variable as a user option. This is obsolete;
nowadays people should just use defcustom.

No big deal. They're pretty harmless anyway.

More specifically it was used to tell M-x set-variable that it could
operate on it.

Nowadays, set-variable automatically considers all defcustom'd variables
as being acceptable, so the * is redundant for them.
