For me it has the feeling of something I would play around with in my free time. But as a drop in replacement I agree, it's a bit of a hard sell for me.
Yup fair enough. Migrating build systems is hard. I've put some work into making migrating from a `go build` project to Please a bit easier. Banzai cloud recently migrated their [Pipeline](https://github.com/banzaicloud/pipeline) project over to use Please but admittedly it was quite a lot of work for them.
