Sounds  painful  on  DVD  media - more minutes of my life that I'm not
going to get back.

You  are  forgetting the scenario where one creates install media, and
uses  it  on multiple installs.   Once once has verified a media once,
is there really justification to re-check on every subsequent install?

Please make it optional, and not the default.
