Issue tidyverse/tidyr#1327 where tidyr::unnest_wider() fails when lists have additional classes appears to have been fixed and has now been released tidyr v1.3.0.
Test DO.utils with tidyr v.1.3.0 without the workaround introduced in commit 3e918c5. If it works, revert that workaround and update DO.utils dependency to >= the latest version of tidyr.
