Transaction propagation

[amaclin1]

I have some thoughts and want to do some experiments.
Am I right that today:

1) segwit nodes do not pull (at all) transactions from pre-segwit nodes
2) all bitcoin miners use segwit clients

conclusion from 1&2 is that

3) the valid standard non-segwit transaction broadcasted to
pre-segwit nodes will not be confirmed at all because it has no chances to jump
to segwit part of network without some kind of "relay-bridge-node".

If I understand @achow101 correctly, it is vice versa. Old nodes send a message to the network, which format they understand. If a Segwit node receives such a request, he would answer with "old format" layout. We had a discussion last reccently here:

Yes, you are right and I was wrong. (But I have to check things again  )
