App download size directly impacts user conversion rates. Because Android 11 and later versions restrict developers from compressing the resources.arsc file inside production APKs (keeping it uncompressed ensures it can be instantly read by the launcher and system notifications), every kilobyte of bloat adds directly to the ultimate download payload. Shrinking the table structurally is the only viable way to reduce this storage footprint.
