Review Comment:
If we do this, doesn't it mean that integers will be parsed as time64s? Is
that what you want to allow? If so can you please explain / write a test that
covers the behavior (so we don't accidentally break it in the future?)

I think you may have deleted the wrong comment here the `/// Batch size ..`
comment should remain and the `/// Optional projection...` should be removed
