/o/ rather than being raised (which would be parallel to it remaining
/o/ before /d/), and that -U in the masculines is from the accusative.
This would argue for my point rather than against it.

in some languages, rather than *-mos (alongside *-mem (Greek -men) and
*-mes). This would then be another instance of *-om becoming -U,
rather than *-os. It would seem also that this development would then
not be dependent on stress (since these verb endings were stressed yet
did not become *-o), and therefore the neuter o-stem ending -o of
Slavic would have to be explained as from *-od rather than from *-óm
(or else from *-o, but I have become aware that this is not widely
supported as credible).
If Schmalstieg's idea (the way I understood it)is right.
that the thematic vowel in nouns is -oN-
(me: PPIE -an- > -ã- > -õ- > -o-;
this must mean thematic nouns were
desinence-stressed n-stems),
then we can strengthen the description of its variation:
PPIE a > ã > õ > o before nasal (which makes more sense
phonetically, instead of just before voiced),
PPIE a > e otherwise.
That would mean that thematic m. nom. is
PPIE *-an-s > *-õ-s -> *-os generally, but
Slavic *-õ-s -> -U
BTW the -o- of *-od could be explained if the voiced
unaspirated were originally prenasalized:
PPIE *-a-Nd > *-ãd > *-õd -> *-od
