I think the main problem isn't the `.replace`, it's the fact that you have to specify exactly which components you want to set to zero - to get "the beginning of this month" or "today at midnight" or "the beginning of the current hour" or "the beginning of the current minute", you have to manually replace a whole list of these components.

I personally haven’t ever had to do anything but get rid of the microseconds field, so maybe my use case is too limited.  It’s a minor inconvenience and I don’t like having to throw away an intermediate datetime, so that’s the main thing I’d like to improve.  I’d also caution trying to get too fancy and complicated for use cases that are already supported or are rare.
