I get where you're coming from, my mouse and keyboard are also still USB-A, but I don't think this is a major issue when you can just buy a decent USB-C dock. I've got one with 3 USB-C ports + display port + HDMI + ethernet etc. I find this honestly much better organizational wise rather than everything leeching from different parts of the laptop, and you're no longer beholden to each variation of laptop having the ports you need (some don't even have ethernet these days...)
