I understand that a subpage starts with a / in front of a link name and there is only one level of subpages for each main page.
Now what happens when you are on a subpage (B) of a main level page (A) and you create another page with a / in front of the link (C)? Is the new page (C) a sibling of (B) or a child of (B) ? Or are both pages (B) and (C) just children of page (A)? See SandBox/MyOwnPage? experiment by someone other than myself.
When you write "Subpages of a common topic can easily refer to each other without a prefix, while outside pages require the prefix" - I get lost conceptually. What is the prefix? Is it the name of the top level page? How does a subpage refer to a different top level page? I may have answered my own question in the above paragraph with SandBox and /SandBox?

For another example, consider a site with pages like:
...In this case, if one was viewing the BrowserProject? or BrowserProject/Bugs? pages, a "/Schedule?" link would point to BrowserProject/Schedule?. If one was viewing the EmailProject? or EmailProject/Features? pages, a "/Schedule?" link would point to EmailProject/Schedule?. In most cases this is what you want, since the EmailProject? would talk mostly about the email schedule.
Sometimes I've wondered if subpages are really worthwhile, but they are useful for some people. They are rather difficult to explain sometimes. --CliffordAdams
I wonder whether anyone has implemented hierarchical subpages and found a good solution to the syntax problems involved. All solutions conflict either with the current syntax or with the DOS / Windows / Unix directory syntax (but this can't be adapted easily). At least there should be a standard among wiki engines to use a common syntax because otherwise there will be a lot of confusion.
We are currently experimenting and use "//" to indicate "down from current page". Everything else is still compatible to the usemod syntax. We tried the more intuitive "./" but dropped it because of its bad readability.
