Best Practices and script/executable directories

Hello,

We're selling an ASP.Net web app to a customer and I've been going through
their requirements doc and they have this recommendation:
Do not place Scripts directories in a subdirectory of wwwroot. Rather, keep
scripts in a separate directory like <IIS_Scripts>.

I've not come across this before so I'm after some theory behind this
practice. Does anyone here have a good link that could help me please?

I can't see how I could move the bin dir from an ASP.Net app's root. As this
is a general requirements doc, this probably isn't aimed at ASP.Net apps but
I thought someone here might be able to educate me.

Cheers for any help you can provide,

Jason.
