I was at the meeting @ko1 is talking about.  Devs at the meeting were not sure if "`each_file` is a useful additional feature to have" you say is real or not.

Do you know if there are cases when taking a random member of such gzip file is actually useful?

There is a similar old issue in Node that I came across that perfectly describes the situation in ruby:

https://github.com/joyent/node/issues/6032

In ruby given the following setup:

```
echo "1" > 1.txt
echo "2" > 2.txt
gzip 1.txt
gzip 2.txt
cat 1.txt.gz 2.txt.gz > 3.txt.gz
```

Calling:
    
```
Zlib::GzipReader.open("3.txt.gz") do |gz|
  print gz.read
end
```

would just print:

```
1
```
