What happened?

Even though they do very similar things, transmute has more options than create:

(base) ➜  conda-package-handling git:(main) ✗ cph transmute --help
usage: cph transmute [-h] [--out-folder OUT_FOLDER] [--force] [--processes PROCESSES] [--zstd-compression-level {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22}]
                     [--zstd-compression-threads ZSTD_COMPRESSION_THREADS]
                     in_file out_ext

positional arguments:
  in_file               existing file to convert from. Glob patterns accepted.
  out_ext               extension of file to convert to. Examples: .tar.bz2, .conda

options:
  -h, --help            show this help message and exit
  --out-folder OUT_FOLDER
                        Folder to dump final archive to
  --force               Force overwrite existing package
  --processes PROCESSES
                        Max number of processes to use. If not set, defaults to 1.
  --zstd-compression-level {1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22}
                        When building v2 packages, set the compression level used by conda-package-handling. Defaults to 19.
  --zstd-compression-threads ZSTD_COMPRESSION_THREADS
                        When building v2 packages, set the compression threads used by conda-package-handling. Defaults to 1. -1=automatic.
(base) ➜  conda-package-handling git:(main) ✗ cph create --help
usage: cph create [-h] [--file-list FILE_LIST] [--out-folder OUT_FOLDER] prefix out_fn

positional arguments:
  prefix                folder of files to bundle. Not strictly required to have conda package metadata, but if conda package metadata isn't present, you'll see a warning and your file will not work as
                        a conda package
  out_fn                Filename of archive to be created. Extension determines package type.

options:
  -h, --help            show this help message and exit
  --file-list FILE_LIST
                        Path to file containing one relative path per line that should be included in the archive. If not provided, lists all files in the prefix.
  --out-folder OUT_FOLDER
                        Folder to dump final archive to
(base) ➜  conda-package-handling git:(main) ✗
