MrGamy [1] filed an adoption request for ttf-icomoon-feather [2]: As a font there is not much need for active maintainership at this time. I would probably move the upstream-url from the polybar-themes repo to https://github.com/AT-UI/feather-font, but since there are no relevant updates to the font at this time, taking maintainership is simply a safety precaution with all that has been happening recently in regards to unmaintained packages.
