I strongly disagree. Modifying content (via addition/sub/ssi modules)
can change enough to consider two pages completely different (at least
as a general rule), so I don't think that they should retain any
I've got mixed feelings regarding xslt module. While I don't disagree
as much, I think it's still safer to remove weak ETags there as well.
