Yes, it would. :-)

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.

FWIW, '-c' is not required by zutils.

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:
