- Gmail doesn't allow me reply to a friend's email, though they could send to me - GitHub would 500 out when adding a GPG key with a UID with Unicode email address - Some services can't outright send the email to such an address
A thread from 2017 https://news.ycombinator.com/item?id=14831756 and one from 2019 https://news.ycombinator.com/item?id=19013617 showed that the support was poor. I wonder how it is in 2022?

Without considering other TLDs (.co, .app, etc.) and domain hacks (del.icio.us itself counts as one, but here it's to make a point), what do you think is the reason of this?
