And if you want to specify different options for gzip? Or a lower compression level for bzip2 based on the size of the files in question? Or a compression program that doesn't use -d? I wasn't saying we *should* do that right now, merely that it isn't hard to run them separately. Despite the current dependency on GNU tar, we are not limited to using only the compression methods it supports, nor in the exact same way it does, nor waiting until everyone's tar has support for some new program, nor adding another dependency on the GNU version in the first place. That's all.
