This is pretty decent. The Playstation default I like as it forces a lot of broken websites (eg. Gmail, YouTube) to work. The downside is adding or changing them does not work. And the CURL and WGET are bad options as they make websites think you're some scraper bot.
Could you please elaborte what you mean by “The downside is adding or changing them does not work”? I do not unfortunately understand what you mean by this.
Having the CLI tools options available is good for testing for the exact behaviour you describe as “bad”. Some sites also hide/modify content from web browsers, but only deliver them to bots and specialized client software for automated processing – feeds/podcasts are a prominent example of this.
