It doesn't mean you will necessarily get "poor performance", you may,
but then it's part of the idea of running BGP: you choose the paths..

But I see your point: it's not simply plugging in an AS number and
announcing the netblock if you're not already running that AS. :)

Right, I hear you.

I guess I am worried about forcing CDNs down the users' throats. I'd
like us to keep a decentralised infrastructure that doesn't depend on
those CDNs and allow people to run their own mirrors.

Hopefully that will still be possible.
