Well, I'd be ok with this, as it lowers the roundtrip problems of 303.
But might take a long time till all tools support it and don't get confused.
Of course not, we only have a handful of tools in the Linked Data realm.
Implementing a new option should still be relatively cheap at this stage
in the game.
A bit offtopic:
I'd rather see people putting information about a responsible sparql endpoint
into the play.
Do you mean the ability to discover On (Green), Busy (Amber), and Off
(Red) re. SPARQL endpoints? This sort of thing is coming, absolutely
critical for SPARQL-FED.
If you have that you can do a lot more / wiser things than
crawling data which is incomplete anyhow (if you dereference a URI you can't
expect to get all triples back, which are relevant for you, try
http://dbpedia.org/resource/United_States (not the HTML page, but rdf+xml
content negotiation and see that you don't even get a label but only incoming
links)).
