That's a decision that must be made by the House and not by the House Administration. The current rules were put in place a long time ago. Some of them reflect the reality of 1867, and much has changed since then. Some of the rules of the House have changed.
If we ever wanted to change the rules, that would be a decision for the House. It couldn't come from outside. If the House wants to have votes, whether they are confidence votes or not, it's the House that has to make the changes. The House has to determine its own rules.
