While your analysis is accurate, it ignores some cases. Some considerations require more work than others. For example, editing to add code tags is something I will judge from the consideration page alone. Editing to reparent a node requires me to look more deeply. I therefore do all the "obvious" considerations first and then return to the ones that need more work. Now, if one of those "obvious" ones uses pre tags or needs readmore tags, having them repeated, even though they are no longer nodes requiring my consideration, makes my work harder as certain things can ruin the format of the page. I agree with both the OP and the suggestion that submit buttons be more liberally distributed. What I can't guess is how much work this change would require, but nonetheless I will say "thank you" in advance to whoever does the work.
