Migrated 3.5y ago - https://f5n.org/blog/2022/switching-to-nextgen/ after getting fed up with having to do a migration.

At that time it was "make my hugo setup run, and remove 90% of the features I don't need" - but I couldn't tell you how much I have diverged, it's really not a lot of code (or dependencies, but I did not reimplement the hard parts, e.g. markdown and templating)
