Others before you have not been shy of doing this - some of them
deliberately, sometimes with ugly blunt imports (*cough*schools in
Mali*cough*) and others just because the imagery they had years ago was
much worse than what we had today. So, there is a lot of precedent for
that.

The fixme (something like "Approximate location, in the viccinity of
this village") is of course a must. Beyond that, my opinion is that the
approximate POI should be clustered around the place=* so that they
appear to mean "this exists somewhere in this village" instead of
having them placed at random positions around where one might think
they are actually precisely there.
