It would also break forwards compatibility in the case new fields
needed to be added.

The only solution would be a libxo-style feature wherein a
machine-parseable format is exposed by virtue of a file extension.

Examples:

1. /proc/pid/stats.json
2. /proc/pid/stats.xml
3. /proc/pid/stats.yaml_shouldnt_be_a_thing
