Because the cache (and the "by_name" sub directory) is common across tests, it's a good idea to make these names as distinct as possible. This avoid name clashes, which makes future Avocado runs to attempt to redownload the assets with the same name, but from the different locations they actually are from. This causes cache misses, extra downloads, and possibly canceled tests.

I see the comment here but it isn't very clear about what the problem is. It just feels wrong to be creating ourselves uniqueness naming problems, when we have a nicely unique URL, and that cached URL can be shared across tests, where as the custom names added by this patch are forcing no-caching of the same URL between tests.
I thought $name was purely for debugging; the file was downloaded in a temporary location, and if the hash matched, it was renamed in the cache as $asset_hash which is unique. This was suggested in order to avoid dealing with URL updates for the same asset. Isn't it the case?
