If the owner of the domain had done it, would it still really be an "eternal issue" since: a. most popular websites nowadays are so bloated that browser caches would throw out many things (including your tiny site that someone checks a few times a week or even longer) a lot sooner compared to how things were about 10 years ago (I presume the default disk cache sizes in browsers have not increased by multiples in this period). b. more people are browsing through mobile devices that are dumped in a few years and replaced with a new one, new browser, empty cache, etc.
