Yeah, that would probably be a good idea.

I'm generally pro sharing code where it makes sense. But I'm also of the
opinion that there are cases where cut and pasteing code make sense.
Some people dismiss cut and paste as never being the right thing, but it
has several advantages that makes it sometimes useful. 

For instance, cut and pasting small amounts of code may be prefered to
adding large library dependencies (that are otherwise unused). It also
lets you untangle otherwise complex dependencies if things at different
layers in the system want to share a small bit of code.

However, in this particular case if we had the plugin system cache i
wouldn't mind having a basic uncompression GConverter that used magic
sniffing and modules for extending to new forms of compression.
