The word "modularization" sounds quite distant, but the most intuitive changes for end users are just two: first, you become increasingly "unaware" of which chain you're operating on, as the entry points are all wrapped by wallets/aggregators; second, when issues arise, it's harder to pinpoint the cause—whether it's the execution layer being stuck, the data layer feeding incorrect info, or the bridge acting up... Anyway, the experience feels like using a bunch of outsourced apps stitched together—smooth when everything works well, but when errors occur, you can only rely on transparency to save the day. Recently, those on-chain data tools and tags have been criticized for lagging or misleading, which doesn't surprise me either—more layers mean longer information chains, and errors are more like "normal fluctuations." If you can only keep one habit, it’s to first check whether permissions/multisig have kept errors out at the door.
