RFC 8040 specifies an error-tag to use.
The claim that RFC 6241 specifies something else is no proof the
WG intended to use that error-tag in RFC 8040.

An errata means that implementations that conform to the RFC are wrong
and need to be corrected.  IMO the change being proposed is not a typo and
there is no other text in RFC 8040 that contradicts the specified
error-tag.

A change of this technical significance that impacts conformance needs to go
through the normal RFC publication/approval process.
