I understand the reasons either of these rules might be problematic to put into the standard, but do we expect that browsers will be willing to drop them? Is it reasonably Web-compatible to do so?

The Web does not assume that client and server use the same encodings. 
Therefore such rules are inherently Web-INcompatible. The sooner the 
implementers can drop it, the better.
