To me, this form of “epistemic should” doesn’t feel like a responsibility-dodge at all. To me, it carries a very specific meaning of a particular warning: “my abstract understanding predicts that X will happen, but there are a thousand and one possible gotchas that could render that abstract understanding inapplicable, and I have no specific concrete experience with this particular case, so I attach low confidence to this prediction; caveat emptor”. It is not a shoving off of responsibility, so much as a marker of low confidence, and a warning to everyone not to put their weight down on this prediction.
Of course, if you make such a claim and then proceed to DO put your weight down on the low-confidence prediction without a very explicit decision to gamble in this way, then you really are shoving responsibility under the carpet. But that is not how I have experienced this term being used, either by me or by those around me.
