My sense from speaking with a rip vendor about this is that yes there is one
target. And that is TR001. I am told for example that TR001 was the CSE
SWOP target. I am also told that a committee looks at prints and the
tolerance values of submitted prints and compares them to a press sheet.
And if that committee decides that the prints look too far away from the
press sheet that vendor can fail the certification. This point is that this
process is not all about numbers.

My educated guess is that it would be close. Considering that Adobe profile
is supposedly based on TR001.
But remember you could get the TR001 Data set and compare that to a profiled
press so your target does not have to be an inkjet.

Your observations seem accurate and that does happen.
Perhaps there are reasons why a rip vendor does not care about being SWOP
certified. Perhaps they only sell into the Photo market where SWOP being
required is more the exception than the rule. Or if they care their audience
might be the CMYK crowd.
As for end-users not getting what they bargained I see that happen all of
the time with both CMYK, SWOP and Photography workflows.
