\pdf??? primitive that can achieve this. (Am I wrong about this?)

Another solution might be the "vrt2" font feature. There's no
difference between the results with or without enabling the feature.
But I do see the font has the feature by using the shell command:
otfinfo -f 

I don't know exactly how it's supposed to look like, especially
kerning, vertical spacing, etc. Just making sure you know about
\applytocharacters:

I didn't know the command, thank you for sharing.


\starttext
   \applytocharacters\rotate{Foo Bar}
\stoptext

as well as \handletokens Foo Bar\with\rotate

Maybe that's already sufficient for your use case.
