I don't think it's necessary and it'll make the help information non-accurate.

Rejected.

I don't see that it makes the help info incorrect. I'm two-ways about the default make target being help. Honestly, most of the time I expect the default target to be sensible, like building the tool or running the tests.
This PR LGTM in that sense

@vbatts Not that incorrect, just not completely accurate.

$ make
Usage: make <target>

 * 'fmt' - format the json with indentation
 * 'validate' - build the validation tool

To me it means "make needs an target, which can be fmt or validate", if we make validate default and target optional, I would like to see something like:

$ make help
Usage: make [target]

 * 'fmt' - format the json with indentation
 * 'validate' - build the validation tool (default)
 * 'help' - show this help information

I'm also fine with changing the default target to be running the tests, just needs to fix help information as well.

@hqhq oh oh, good catch. so yes, using square brackets there would be more accurate 😸

@hqhq Thanks for your advice, updated, PTAL.

LGTM
