Is it necessary to squash commits into a single commit?

You advice to

squash your commits into a single commit

Is it necessary? Because history is erased.

I think that is is a case of people trying to avoid "Too Much Information". Personally, I like to track all of the missteps as well as the final solution--the "true history". But some people regard that as so much clutter. They only want to see the final result.

I think it depends on us, however most organizations look to a single commit.
