The parsing code of repl_gram.y represents zero maintenance at the
end, so let me suggest to just live with what we have and do nothing.
Things kept as they are are not bad either. By changing the default,
people may have their failover flows silently trapped. So if we change
the default we will perhaps make some users happy, but I think that we
are going to make also some people angry. That's not fun to debug
silent failover issues.
At the end of the day, we could just add one sentence in the docs
saying the use of ANY and FIRST is encouraged over the past grammar
because they are clearer to understand.
