> I don't see a (big) advantage over specifying `vlicense …` somewhere in `do_install()` or `post_install()`. You may save at most 2 lines in a template. And you cannot handle cases where the license file is created in e.g. `post_install()` from cropping some README.md, index.html or other source file.

The license file can still be created in `post_install()`, if `common/hooks/README` is accurate; the license hook will run after `post_install()`.

A `license_file` variable simplifies a very common use case for `post_install()`. Sure, it only saves two lines, but it makes the template a bit easier to read. (Assuming, of course, that the most common goal in reading a template is not to determine how the license is installed, but how the package is build, installed and packaged.) For more complicated license installations, specific templates can still opt to omit `license_file` and manually invoke `vlicense`.
