I don't think it should be enabled by default. It's common to expose
keepalive and other TCP settings as an option, like libpq does, but it's
not usually enabled by default, and it might be an unwelcome surprise to
some existing applications.
In particular, if you have a dialup connection, you do *not* want an
idle connection to keep sending periodic keep-alives, because keeping
the connection open costs money. It's not as big a problem these days as
it used to be, but still.
