That's a 72MB download, and yet another way to fragment the ecosystem. Not something I'd get just to make a package when a default Python setup has recommended tools and everything I need to make and/or install packages.

No it doesn't. Neither setuptools nor pip are part of the standard library. Yes, they are installed by default in many cases, but they are still "extra tools".
72MB? On a development machine? Are you on dialup?
Poetry doesn't fragment the ecosystem. Unlike setuptools it uses pyproject.toml, which can be read by other tools, and is the correct way of storing package configuration.
A package built using Poetry is installable without Poetry in the exact same way as one built using setuptools.
I think it's the right direction, and I look forward to Poetry maturing. But right now it has a lot of gotchas, and I would only recommend it for people who are serious about dependency management/compliance/reproducibility.
That's if you want to pin transitive dependencies, which is the de facto standard in JS world but not always true in Python world, depending on your context.
Which, like any jazzband project, you must not use for a commercial project, as stated by their CoC, the Contributor Covenant with a vague & bizarre modification about ethical use at the end. You are simply not allowed to contribute in any way on any kind of paid time, nor are you allowed to pay someone to contribute. This is of course not advertised for when they tell you to give them your OSS projects, for which you have already chosen a license and maybe even a CoC for. For this reason, despite the many non profit projects I maintain, I stay away from jazzband.
