I can answer the second part -- I don't think that it's a good idea, but I have tried it in practice. Because RDF changed its Namespace URI at the last minute when it went to REC, there are major deployed RDF document bases (especially RPMFind and DMOZ) that use still the wrong Namespace URI for RDF, and cannot easily change to the correct URI now because they're trapped by deployed software. In two separate projects, I tried implementing support for the legacy (incorrect) Namespace URI, and doing so was trickier than I expected, because it complicates the simple hashing schemes that are necessary to process Namespace-qualified elements efficiently. For now, I've decided to support only the correct RDF-Syntax Namespace URI (the one in the final REC), but I don't imagine that DMOZ or RPMFind will be able to become conformant any time soon because they have extremely large user bases with the old Namespace URI hard-coded in their software.
