The working group considered well-known URIs during discussion of service description discovery (see "Option 3" in [1] as a starting point). There was very little support for the idea[2], and we decided to proceed with the current discovery mechanism of using the service URL to return a service description. For the issue to be reconsidered, I think we would need to see an proposal for what metadata you think should be returned from the /.well-known/sparql URL, taking into consideration the potential presence of multiple endpoints within one http server and RFC5785's suggestion that such a resource only return metadata (potentially making it a poor choice for a service URL).
