we could remove the port, and re-import later if someone has an updated version...
I think that's what should be done. I really don't have the time or energy to update this port. The last time I spoke to the maintainer, I think he told me that new ports needed to be added to update this one. He sent me an unfinished draft. It's a shame I lost the emails due to a problem with my self-hosted server. I've used it occasionally on Linux to share files with my smartphone, but on OpenBSD the safest (though less convenient than Onionshare) way is to use OpenSSH to copy files from one device to another with Termux.
