Ordinarily I would agree but, in this case, I'm not convinced that the
backwards compatibility problem is a significant issue. Specifically,
I have not seen (and did not see anything in the examples linked to
within the other thread) any existing cases of 202 that would conflict
with this approach. Should the Content-Location header be excluded
from the 202 response, it would simply be handled as it is today.
Currently, the use of Content-Location in a 202 is rather undefined
and left wide open to interpretation so there's really no solid
precedent to fall back on or conflict with, it would seem.
