However, the specialized code will still be more efficient:
```java
// Even when Curator's minimum supported Java version becomes
// no less than Java 12, where finalize() methods are removed
// in Deflater and Inflater classes and instead they are
phantom-referenced
// via Cleaner, it still makes sense to avoid GZIPInputStream
// and GZIPOutputStream because phantom references are also not
// entirely free for GC algorithms, and also to allocate less garbage
// and make less unnecessary data copies.
```
