As long as the timeout is much longer than normal POST times and the countdown stops as soon as a key is pressed (so slow typing is fine as long as the first key is pressed quickly i don't see this being a huge issue.

this is a legit one but its a pretty special use case imo

otoh you could stretch that case to say that using the installer should require sufficiant arcane commands that a child can't cause trouble with it, i don't think that is a road we should go down.

but if you are leaving the CD in and you want the machine to be usable then you are going to have had to disable CD booting anyway.
