do we need this (and similar) guards? surely we're already only calling functions like hydrate_block_anchor when we're hydrating. rollup is smart enough to deal with it

Depends on the method, in this case there's no if block at the call site because it would result in more if block code overall.

This is what I was talking about last week in our call. I wasn't seeing the tree shaking working as expected by Rollup. However, if you put into this boolean guard then it works great – something I didn't do.
