As per title.

Place any minekea barrel, spawn villager, watch him ignore it.

I didn't even think to make them POIs for villagers, but that's a good point. I will see what needs to be done for these to work the same as a normal barrel.

Thanks for the report!

BTW.
Interested to know how you do this, I have a barrel mod also and it was working in 1.18 but POI stuff got changed and doesn't work in 1.19 :(
For info, here's how I did it in 1.18

Sorry for the long delay on this. I have it fixed in dev and will push this out in the next release. If you haven't managed to get it working yourself yet, take a look at the Reinforced Barrels mod. Those barrels function as villager POIs, and my new code is almost completely copy/paste from theirs.
