No, it doesn't match `/rootnotroot/service1` (or it least it should not).
You are right, that `pathPrefix(string)` only matches a prefix of the
string, but it also matches a leading slash. So, if you are using the
recommended `pathPrefix("xyz") { pathPrefix("abc") { path("innerMost") } }`
pattern, then the problem you describe is never a problem as the only path
that is matched is `/xyz/abc/innerMost`.
The only place where it would matter is if you complete a route from a
place where not the whole path is expected to be matched, i.e. there's
still something left in `ctx.unmatchedPath`. Is that what you are doing?
