Try browsing the web with non-default colors set in your browser, with a default font size that's not 16px, or with a 13px minimum font size set.  These aren't exactly hard things to deal with, but authors just don't deal with them.  I sincerely doubt they'd deal with the possibility of a websocket not actually opening unless is was _very_ common.

That wasn't what I meant.  "it won't happen often" I meant, the need to have a queueing mechanism written in Javascript.  i.e. most applications of web sockets would want to just fail.  The few that do not, can roll their own.
