You're assuming that it takes significant time to parse HTML. However it might be that that time is insignificant compared to the time required for something else, e.g. the time required to layout the text on the end-user's window.

Internet standards don't happen by having a single body (the w3c) implementing something and declaring it a standard. Instead, internet standards happen by having multiple independent bodies creating multiple implementations. A consequence is:

• Some people have developed something that isn't standard yet (i.e. they're ahead of the standard)
• Some people haven't yet developed something that is standard (i.e. they're behind of the standard)
