Currently all the manpages are packaged as part of lorax. But some of them, like composer-cli, should actually be included with their subpackages so that they can be installed independently.
Note that this was fixed upstream in commit 7f562db31ff03af2acd3b493c73d36527bb412f7
# rpm -q lorax
# rpm -ql lorax | grep man
# rpm -q composer-cli
# rpm -ql composer-cli | grep man
