The default nenv uses exact version matching to find a prefix as intended. However, you can use symlinks to create as many aliases for the current nenv as wanted, including the use of prefixes. This is not technically a hack as the rbenv family of environment groomers all work by using the directory name to set the version, and in many of these have a plugin similar to rbenv-aliases / phpenv-aliases even automatically creates symlinks to partial versions for you. In some of these, such as jenv, however, directly manipulating the prefix directories with symlinks is a recommended / common workflow.

So please indicate that partial versions is supported for nenv through the use of prefix symlinks.

I am the maintainer of phpenv [1], and a contributor to nenv [2] and jenv [3]. I am also the maintainer of phpenv-aliases [4]. If needed, I will clone an nenv-aliases repository right now.
