I don't feel bothered at all. Your letter could
make an impression there is a lack of help and
google not working, but it's not always true.
So, sometimes people probably wait to see, they
will only help and not do all your work.

Without this there is a possibility the route could be
changed during connection.

Maybe it's intended for something even more advanced,
I don't know. I checked this long time ago and later
seen someone was trying to fix something around this
- so I don't know what is the current state. But you
are right - this should be better documented.
