This, I believe, was originally set forth because the Senate was modeled as an “upper house” not subject to the whims of popular agitation (6 year terms vs 2 year terms. Appointment/selection by States vs direct election by district constituencies). The House, having more direct connections to the people is given the power to investigate and impeach a president, hopefully as a reflection of the public. The Senate, being composed of elder statesmen and slightly removed from the direct consequences of local constituents, is to be a check on potential rash impeachments.
So I’d dare say the impeachments were worth the paper the constitution was written on. The House impeached. The Senate tried, and acquitted him.

What never would have happened? Some bizarre unknown chain-of-events which led to Trump staying in office? The occurrence which DEMs are somehow taking the heat for is the GOP outnumbering them and outvoting them in the senate to keep Trump in.
It is nothing, because nothing came of it.
