You are perfectly right.  If it were up to me I would recommend to
keep all those characters that were considered as duplicates.  I quote
here from this page[^1]:

     A false distinction was introduced to Unicode between the oxia
     (acute) and tonos, resulting in wrongly duplicated code
     points. See Greek Unicode duplicated vowels for a full
     discussion.

So strictly speaking, oxia alone is not yet removed from Unicode.  But
as alpha, epsilon, eta, iota, omicron upsilon omega with oxia were
allegedly deprecated *and removed* from the Greek extended range, I
would say that oxia alone does not have much to live.

That, according to digitalclassicist.org, of course.  I will try to
see if I find anything of relevance on unicode.org and report back.
