If required, I think that we have already included the minimum
information necessary for the primary diagnosis, including locations,
within the primary messages. Here is an example:

> LOG:  00000: invalid record length at 0/18049F8: expected at least 24, got 0

And I believe that CONTEXT, if it exists, is augmentation information
to the primary messages. The objective of the precedent for the use of
relname_only was somewhat different, but this use also seems legit.

In short, I think the distribution between message types (primary and
context) is fine as it is in the latest patch.
