I personally don't care either way about this change. But:

I'm not too concerned either. There's plenty change of the WAL contents
across versions anyway. We shouldn't break things gratuitously, but we
shouldn't hesitate to make the format better either.

If somebody really wanted something that parses reasonably across
versions I'd like to a) hear that usecase b) come up with an output
format that's oriented towards that.
