I didn't check all the Tapestry code I wrote in the last few years, but I'm pretty sure I used BeforeRenderTemplate and BeforeRenderBody to abort the rendering of template and body. Removing the rendering would definitely loose some flexibility. Because the rendering state diagram would look like this:
BeginRender -> RenderTemplate -> RenderBody -> AfterRender it wouldn't be possible to skip rendering body while allowing rendering of the template. If you skip template rendering, you automatically skip body rendering. Having said that I'm against removing these methods.
