Seems quite useful. Will definitely check it out.
Minor nit: 10MB really isn’t that “small” for a CLI. I’d looked at your go.mod and seems like the most of dependency bloat might be coming from cobra or viper as it has in-tree plugins. You can check out an alternative like https://github.com/knadh/koanf which would decrease the binary size, I’m sure.

App init and graceful watch lib recommendations ?
For configuration, I like Koanf.
-
Two ways to provide configuration: command-line, yaml file.
Of course. You should always use a good config package. caarlos0/env is okay but https://github.com/knadh/koanf is a better all around solution imo.

You can also use Viper with urfave/cli, or you can replace Viper with knadh/koanf, which I personally prefer.

Viper – Go Configuration with Fangs
Use viper with care. It has some dangerous fundamental flaws [1]. We got bitten hard, submitted a PR [2] and followed up for a year and a half to no avail, before I went ahead and reinvented the wheel and wrote koanf (plug), specifically to avoid viper's flaws.
Most importantly:
- Breaks JSON, YAML, TOML etc. language specs by forcibly lowercasing all keys internally. Dangerous because it can silently merge differently cased config keys into lowercase.
- Hard codes big unnecessary dependencies into the core, significantly bloating build sizes. No separation or abstraction.
