Do you think to enable VisualHostKey of OpenSSH by default is a good idea?

VisualHostKey is a new feature of OpenSSH introduced by version 5.1. 
It seems very useful for users who need reinstall system sometime.

Visual fingerprinnt display is controlled by a new
ssh_config(5) option "VisualHostKey". The intent is to render
SSH host keys in a visual form that is amenable to easy recall and
rejection of changed host keys. This technique inspired by the
graphical hash visualisation schemes known as "random art[*]", and
by Dan Kaminsky's musings at 23C3 in Berlin.

For example:

~]# ssh 10.12.10.226
The authenticity of host '10.12.10.226 (10.12.10.226)' can't be established.
RSA key fingerprint is 9b:2a:c2:2d:41:24:b1:92:95:e6:34:48:4d:01:19:57.

Are you sure you want to continue connecting (yes/no)?
