Would it be too much to ask for free compressor support?
Yes, it would. :-)
By free, I mean any defined in zutils config file in the way it is now:
zutilsrc just allows changing the command used to decompress each supported format, but it can't be used to define new formats.
Adding a new format multiplies the troubles because every decompressor has its own quirks, like undocumented exit status or skippable frames.
It would be required for decompressor to understand '-d' as 'decompress' and '-c' as 'to-stdout' options, as mandated by tar.
FWIW, '-c' is not required by zutils.
It would solve all the future requests for another fancy compressor support - could be solved by adding de/compressor to the config file.
What you ask requires the redesign of zutils. Currently adding a new format requires making changes to most source files. For example to extend the command line options:
