If it's avoidable (and on very static type pages like this, it should be) then yah. Keep in mind that what seems easy to you may be wildly new territory for others. Just because you're technical doesn't mean you know the ins and outs of running a server.
This site fell over with minimal attention.
I'm a broken record on this, but people should not blame Wordpress for the continual pattern of poorly configured Wordpress instances, as the platform is built to have a caching plugin of one sort of another: I have Wordpress instances that serve enormous loads without breaking a sweat (even on AWS micro instances), all courtesy of absolutely rudimentary functionality of W3TC.
Seriously, when you submit your own stuff there should be a checkbox acknowledging that you have basic caching in place.
