Just like syscalls, vdso functions with new APIs/ABIs should have new names. For example if a version of clock_gettime for a new userspace with 64-bit time_t is added, it should be called clock_gettime64 (with a corresponding __NR_clock_gettime64), not offered as a versioned symbol over top of the old one. The versioned symbol approach is a lot more confusing and as far as I can tell offers no benefits.
