I think the underlying motivation in this comment is that there are very many technical application development challenges which can be solved simply by web developers paying close attention to the fundamentals of their craft rather than relying on "fancy tricks" to speed up the development process. Plugins like Flash used to be one kind of "fancy trick" to offload into another layer, but there were many developers who stayed faithful to the process of working with everyday browser capabilities (and all of the politics that these capabilities entail), so that the wrinkles could eventually be ironed out. I think that so many who go the "Electron"-ic development route are afraid of getting their hands dirty with the question of in-browser client-side storage, ie, they want to be able to get their hands quickly on the files in the user's native file system.

There are, however, very stable in-browser ways of dealing with the question of client-side storage. IndexedDB is one. But there is another that I am quite partial to, called the File System API. I use it to locally store the files and code in the browser-based OS called Linux on the Web (https://dev.lotw.xyz/desk.os).
