No, they are not incompatible, which is why we by default allow
building Emacs with support for both.  But there should be no real
need to use m17n-flt if HarfBuzz is available, as we aren't aware of
any use cases when HarfBuzz does a worse job.  (Using m17n-flt in a
build that has it compiled in requires the user to specify non-default
frame parameters when creating frames, otherwise it will not be used.)
