... isn't that just the load/store intrinsics? (see the printiv64/printfv64 in https://github.com/rdolbeau/EPI-test-codes-vector/blob/master/simplefft16-rvv/test_fft16_zgemv.c)

The 'easy' way for printf would be a vector 'Length modifier/Conversion specifiers' to signal vectors so that printf can deal with them directly. Would be convenient, but then users will request all the already existing modifiers (width, precision, display style, ...) and then request some brand new ones (field separator between vector lanes, ...) ...

I agree with you. Vector store is enough.
