In cli, why no option named "--output-file-name" ?

[SprayHank]

Feature request

add the option named "--output-file-name", and I think the function is very clear from the option name.

What is the expected behavior?
Can specify the output file name without a configuration file
What is motivation or use case for adding/changing the behavior?
Can specify the output file name without a configuration file
How should this be implemented in your opinion?
I do not read the source code yet, so I do not know now.
Are you willing to work on this yourself?
yes

Please run webpack --help, we have webpack --output-filename ./my-file.js
