Yep, ticket created by me to get it fixed, quickly hopefully. The plugin repository has been run very badly. I had to create a ticket to get Resilio Sync updated when the version in the repository was over a year old! And now this with a 32bit version put in there! It's not like it's the appstore with billions of software! Doesn't instill much confidence in a product when it's handled this badly.
Sure it's possible: https://github.com/freenas/iocage-plugin-nextcloud/pull/13 (it merged cleanly when I submitted it over four months ago--they've made another commit to the plugin since then (which only serves to make the plugin more broken) that results in a conflict). In case the PR didn't ping the right people, I submitted a ticket a couple of weeks later, which has yet to be screened.
It's open source, but it's their repo, so they have to merge it.
