...and using XML introduces a dependency for those that apps that don't already
use some XML parser. I realize that since the pool of apps that care to
mechanically parse EXPLAIN output is small, it wouldn't necessarily be a big
deal to hand each of them a new dependency in the form of a parser for XML,
JSON, etc. But we know the least common denominator is to return a set of
tuples; let's make sure that really is unworkable before forcing even that
dependency.
