With the caveat I only have the package installers usage data for Wagtail downloads – pdm usage has fallen off a cliff, from 0.2% of downloads in January 2024, to 0.01% in January 2025. Roughly matches the uptake of uv.
Doesn’t make pdm bad in itself but that means there’ll be fewer pdm users around to report bugs, potentially fewer contributors to it too, fewer resources, etc.
Indeed, on one hand PDM works great, but on the other hand we wouldn't want to choose a package manager which might not be maintained anymore after a few years because there are just not many users of it.
