I'm not disagreeing that's a bad aspect of IPv6, I'm just saying that it's not that big of a issue for its adoption.

Wait till you find an application that accepts 1.65793 as an IPv4 address. Or 134744072.

  $ ping -c 1   1.65793
  PING 1.65793 (1.1.1.1) 56(84) bytes of data.
  64 bytes from 1.1.1.1: icmp_seq=1 ttl=54 time=1.56 ms
  
  --- 1.65793 ping statistics ---
  1 packets transmitted, 1 received, 0% packet loss, time 0ms
  rtt min/avg/max/mdev = 1.560/1.560/1.560/0.000 ms

(by the way, this was way less of a dumb peculiarity back when IPv6 was designed)
