Sometimes you need that extra stuff for your application. Obviously I don’t know what exactly the author is running but I have some experience with sysadmining applications on embedded devices.
You don’t always have the ability to say “we can’t do this because of x y and z reasons” because that you’re calling out is the primary revenue source and no one wants to take the time to improve and optimize it.
I hate that fact very much but that’s the reality of business and living in a scarcity society. So you make other decisions and free up anything else you can.
You also point out 4000Mb,the author states and I agree, it’s not uncommon to see 2000Mb or even 1000Mb. That 3% starts to become more problematic.
If the design cuts it so close that it can’t spare 1% of RAM, the system is in danger of crashing in production due to memory exhaustion.
Sure, at some point the impact of systems will matter and you should choose something else. At the point, you may also want to reconsider traditional Linux altogether in favor of a special low-memory variant or alternative.

It was not even 3%, it was a tenth of that: 0.3%
Even with 1GB of RAM, it would be 1.2%.
