Thanks all for the feedback, To reiterate my position — I can alter my compilation code for my Garmin- compatible maps to prefer destination:ref over the plain ref tag. That's not the issue here. I don't believe it's correct to add a ref tag to an unsigned way, especially a freeway exit ramp. Logan airport service roads may indeed have legitimate refs and that's perfectly fine. These are exit ramps for Exit 49 — they do not have standalone refs either signed or unsigned.
Also, it isn't just my routing code that's misunderstanding the tagging of this interchange. OSMAnd displays the identical message when approaching Exit 49. Do you think it's a good idea to request that both me and OSMAnd make special allowances for this tagging scenario? I want to remove the references but I anticipate some blowback from the original mapper. That's the reason I put it out for other mappers to consider.
