-test value used for HBase block size?

I have a question...
HStore ctor used by HRegion does: this.cacheConf = new CacheConfig(conf,
family); which calls CacheConfig.instantiateBlockCache(conf) and creates
BucketCache, LruBlockCache and DoubleBlockCache depending on config.
However, BucketCache in ctor, as well as CacheConfig when creating others,
uses StoreFile.DEFAULT_BLOCKSIZE_SMALL as block size (without getting from
config or anything).
DEFAULT_BLOCKSIZE_SMALL is described as:
// Make default block size for StoreFiles 8k while testing. TODO: FIX!
// Need to make it 8k for testing.
public static final int DEFAULT_BLOCKSIZE_SMALL = 8 * 1024;
Should it be 8k? Am I missing something? It's been like that forever (at
least the constant, didn't check the usage).
