I would say so, to say the least, but I am still investigating.  What
is sure is that tonos originally does not encode the same as oxia.
The former encodes a stress, while the latter encodes a pitch.  This
is undisputable.  That said, the fact that the Greek government did
decree that tonos shall be the same as oxia (to be taken cautiously, I
am not a specialist of modern Greek) surely introduced a lot of
confusion.

For example, if one makes no distinction between the two, then it
becomes harder to analyse large corpuses with a computer.

Well that is not very friendly...

Just the same on my side.
