What percentage of your development effort will you budget to serve that 0.2% client? Would it be more than 4 hours a year? How much extra support would the types of clients who actively turn off JavaScript require? How much extra business will these types of clients generate or influence?
I am not saying it is not worth the effort, but I am saying you should clearly set expectations and measure to be sure that this juice is worth the squeeze. If your motivation is because it is the "right thing" to do and not because you can quantify that the effort is worth it, then it almost certainly is not. On the other hand, your business analysis might show that this type of client is 10x more likely to subscribe/buy your product and supporting them is a no brainer.
Note, that I am assuming we are talking about a smaller client base and dev team. Social media size sites might for example consider this 0.2% of their perspective userbase as a critical mass and devote thousands of hours to supporting them. You might also feel in your case that the use of JavaScript hinders assistive technologies and their support is critical to your success.
For what it is worth, I do not disable Javascript myself, nor do I build sites that specifically work without it though I do try to build clean HTML to the extent it is practical and I would rather solve a problem with CSS than with Javascript.
