Yes, that certainly addresses the known practical issues.

In general, I think that the more complicated null handling gets, the more potential security issues there are. The recent security problems with nulls that I know of were all caused by stripping them in tokenizer instead of passing as is, which some software did, and some didn't perform. Converting nulls to U+FFFD will be a unique trait of HTML5 processing, so it will likely always remain an unexpected feature for many.
