I have implemented a "redirect to section" feature. It requires JavaScript, with the old behaviour maintained for non-JS browsers.
Use it wisely -- remember that a link from one page to the middle of another will typically be unexpected and surprising behaviour for the reader, especially when the source link has no # in it. This feature is regularly requested, and so I implemented it on that basis. I'm sure there are good applications, but some amount of common sense at the editorial level is required.
