Roadmap to turn on rehydration by default

[sdhull]

This is a list of things needed to be able to turn on rehydration by default.
Primary objective: turn on rehydration by default (and not have it produce weird/unexpected results in a majority of apps)
Hurdles:

• rehydration markers rendered in tags that shouldn't have them
  • <title>{{title}}</title>
  • <style>{{style}}</style>
  • <pre>{{pre}}</pre>

What am I missing here?
