It's actually very relevant. If you wish to have more features, great UI/UX, then you need more developers, best developers, you also need a budget to pay them from, you need investments and you need investors. If you want to have investors, you need to create good investment environment without pitfalls. That's why you need low to zero inflation. Imagine trying to persuade someone to buy stock knowing that there will be 10-200% inflation on it. He will just laugh at you! Only exception would be if you can expect value growth 1000%. per year (and not growth in users, growth in value). This is currently pure fantasy. And if this happens somehow in one year it's not sustainable long-term.
