To be honest I don't think this part of documentation is perfectly related to my question. What I am thinking is if part {#feedItem.title} is really rerendered or at least somehow processed internally in other scenarios than if title was modified. In any case it wouldn't be bad practice to put unbound expression. The question that comes from my thoughts is: Is bound expression impacting performance even if unrelated attributes changed?
