The curious thing is that not all kern values are affected. I played
a bit around also with latex examples (and luaotfload) and got a
different value only for va but not for VA or Va:

pdflatex:

\hbox(16.99782+0.0)x96.45274, direction TLT
.\OT1/cmr/m/n/24.88 V
.\kern-2.59966
.\OT1/cmr/m/n/24.88 A
.\glue 7.51096 plus 3.89554 minus 2.60223
.\OT1/cmr/m/n/24.88 v
.\kern-0.64993
.\OT1/cmr/m/n/24.88 a
.\glue 7.51096 plus 3.89944 minus 2.59964
.\OT1/cmr/m/n/24.88 V
.\kern-1.94974
.\OT1/cmr/m/n/24.88 a

lualatex
