Some of the first stars from the formation of the universe may stillexist today

Look up "the G subdwarf problem." If stars much less than a solar
mass formed early, they would still be present today. Moreover, if
the early IMF were anything like today's, there would be lots of
those stars in the solar neighborhood. We don't see them. This says
the early IMF was nothing like today's; there were few if any
low-mass stars. Of course "few" is not the same as "zero," but
existing surveys put pretty strong limits on how many such stars
there could be compared to the massive ones (presumed to be)
responsible for reionization.

It's possible that not all supermassive stars produced sub-dwarf
companions, or if they did, some may have swallowed them again after
formation.
