I don't know, since I never used such path. I think it is resonable to ban
them, especially considering that no Windows user ever complained.

No, there's no "offiial" way. However, you can use a variable which would be
set to 'true' in the test code for path.jam.

I know that there are some asserts in the build system code, for example, in
the generators module, so generally its OK.

Just make sure that each specific assert indicates a programmer's error, not a
user error. The asserts in generators sometimes trigger due to user's error,
which is bad.
