Yes, we are already running this in production, works as expected.
In some places we explicitly compare tasks and for ~100-1k tasks, we definitely see a difference (well, just our subjective feeling). |

Now let's pray we didn't break anything. :) |

Description, Motivation and Context
Currently,
Task.__eq__works like this:luigi/luigi/task.py
Lines 543 to 544 in 1192003
param_kwargsis a dictionary, so task comparison might be slow for tasks with many parameters. It should be safe to just compare thetask_idwhich is computed in the task init based on all parameters and therefore is a valid hash for task comparison.(originally added in #2446)
Have you tested this? If so, how?
No new feature was added, so the existing tests should completely cover the code changes.
