House Speaker Contest

Regarding the concessions that McCarthy apparently made (to no avail), can anyone tell me why reducing the threshold to vacate the chair from 5 votes to 1 vote was so contentious? Presumably if you are going to have any chance of getting a majority vote to kick the speaker out you could round up 5 people to put through the motion. Allowing a single member to put it in motion would just mean that everyone wastes an hour voting on a doomed measure. I guess I can see why the members of the freedom caucus might want it since it gives them an individual unilateral opportunity to get TV time by making an ass of themselves, and I can see why McCarthy (and anyone else sane) would oppose it as a waste of time, but in the grand scheme of things it just seems like a very small hill to die on.
