I don't agree that there should be an article on
each such abbreviation;
however, if there is no article, one should just write out the abbrevation
in almost all cases. I tend to write out abbreviations like "etc.",
"i.e."
and "a.o." whenever they occur in an article I am editing.
This is a sensible position. I would tend to make such changes in most
cases, but I would hope that eventually each of them does have an
article on Wiktionary. Of the given examples, I tend to leave "kg" and
"etc." alone, I have mixed feelings about "i.e." where most English
speakers would understand "id est" even less, and I don't know what
"a.o." means. I have to guess that it means "change it".
