Unfortunately this is the only real solution. All other solutions with
a simple trailer/tandem can (not) pass wont help in reality, because
reality isn't only black-white.

Of course there are in reality very dark-grey cases there you clearly
can say that a tandem can't pass. But almost my case 1) you can't say
definitely, that a trailer can pass or not, because you don't know the
with of the trailer.

To your 3): The router can make such assumptions, because he decides
for which kind of bicycle he calculates the routes. The router can
tell the end-user for which kind of vehicle the route is calculated,
the mapper can't do that.
