I have tried the #2 as specified below. I kind of agree that #1 will
result in the desired behaviour.

I tried this and here is what is happening.

I launched emacs then I launched another frame and M-x erc-tls and come
back to the 1st frame for other work. "erc-tls" running fine in the
other frame but when it starts to join autojoin channels after
connecting, it creates one more frame for each channel instead of
reusing the 2nd frame.
