Ok with me, assuming that you've tested with GCC 13, 14, 15, with 
configurations where GCC actually does do vectorization (presumably with 
RVA in the -march baseline). (If there are bugs in e.g. GCC 13 which is 
fixed in 14 or 15, we can of course also adjust the version criteria per 
architecture.)
