I believe many people should attempt to create their own web extension, even if they don't publish it.
In my younger years, I used to crack and hack software just for fun. Those were my Softice years. Later, when Opera was not Chromium based, I also had several site customisations, since it was very easy to add my own JS and CSS to any web site.
Nowadays, I have 4 extensions created and tailored for my needs. One that deals with cookies (mostly "delete everything" outside of my white list) and three that add functionalities to specific sites (automating, managing lists, hiding or highlighting content, etc). Building them was fun, though not as much fun as playing against "copy protections" long ago: like going from competitive chess to creative DIY.
The only pain with custom made extensions is that Firefox is very reluctant to load them. I don't want to upload them them on some Mozilla server, so I have to enter some cryptic "about:..." URL, then click and navigate to my extension, for every extension at every browser start. This is one of the main reasons I'm using more Vivaldi than Firefox these past months.
