I mean, yah. If you're going to be baking enough to merit 10kg of multiple flours, you absolutely want them in separate containers. Even if you only have the AP, bread, and cake flour trio that covers most baking needs, you'll want them stored in airtight containers.
It ain't even that hard or slow; my crippled ass with arthritis can do it fine. Well, it hurts, but I don't lose enough flour to matter.
