One thing to take into account is that there can also be links from off-wiki, so we can't fully control for breaking them if we change things--that's why we leave redirect pages around when pages are moved/their names are changed, and also why we try to avoid changing heading names (obviously this is going to happen sometimes if there's major restructuring of a page or something, but I think fixing capitalization is considered minor enough to be not worth that cost)
