When someone tells me to arrive 3 hours before my scheduled departure time, to me it's disrespectful that they would waste so much of my time so unapologetically.
Other people might see it as no big thing, an enjoyable chance to sit and read, or do some people-watching, or a comforting safety margin.
When someone tells me to take off my shoes and belt and shuffle through a metal detector while they take my wallet and keys out of sight, under the constant threat of even more intrusive searches - to me that's extremely undignified. There's no other situation in my life where people can control what I wear, or presume to separate me from my keys and wallet.
Other people might feel reassured by the process, or see it as no different to going to a swimming pool.
When someone demands I walk a needlessly winding path through a maze of tawdry shops selling overpriced perfume, to arrive at an uncomfortable seat surrounded by garish billboards.... you get the picture.
Upon further testing,
still offers up my public key on my system (macOS, OpenSSH_9.6p1, LibreSSL 3.3.6), contrary to what StackOverflow and the Internet seems to think. Tested by hitting whoami.filippo.io, linked in child comment.
