I agree with your suggestions , but I don't think that most of the newbies who are having low amount of Bitcoin are making transaction more , they usually use Thier btc at trading exchange to make trade with altcoins .
But still here surely it is much beneficial for us to use segwit wallet because with it at about less then 0.1$ fee we can get better speed of confirmation in the transaction of Bitcoin easily .
Edit 1:Here another things that we are seeing that people are not having idea in Thier mind that they can.move toward the another option with the same.coin ( i.e Bitcoin ) to get better and faster confirmation very low fees because of the main reason of non-proper guidance ( as you said ) .
Here we need to remain with the updated with new new things , and here you are doing the same .
So thank you for this share of old but beneficial thing which is a big need for newbies in the present time .
