This is surprisingly large in the uncompressed binary, especially with ICU linked in. It seems likely that getting rid of unnecessary strings, shrinking unused arrays, and deduplication efforts could potentially give us some wins post-compression, but we should try compressing a binary with the data section manually removed to see how much space it's taking up post-compression.
