An XML processor is allowed to ignore incoming comments in its processing.

Wrapping it in CDATA will mean the processor won't recognize it as a
comment because it is a string, the processor will preserve the
CDATA, will emit the text, and the resulting text would be
interpreted as a comment by a downstream processor.
No risk of losing the data on input.
That's my guess ... I've not seen this done before, myself. Interesting.
