The French tax system is pretty simple. Taxes are high, but simple. The website you use to file your taxes is also pretty simple, and every single field has a button that explains what it is about and in which cases you should write stuff inside.
The only annoying parts are if you have accounts outside of France, you have to declare them. And if you get dividends/capital gains in foreign currencies outside of the EU, you have to calculate yourself how much tax you owe using a bunch of tables per country and currency.
80% are just boilerplate text with one text box per page. It's shitty paperwork but it's not 644 pages of tons of input. There person you're replying to probably owns a business or works in multiple states or something goofy like that. They're on the upper end of complicated

Yes, and? Nobody would fill all annexes. They are annexes because they're not part of the common path, and are only needed in specific scenarios. Their length is kind of irrelevant.
They make even the simple case more complicated than it needs to be. In these other countries, most people don't need to file anything, it just works with what the state already knows. You don't have to provide a load of supplementary info to get the correct outcome. I can only guess you think this way because you've not done taxes in another country.
