From urbit/bridge#1074: the Bridge guide does not talk about Urbit ID's ERC721 compatibility at all. The IDs can be "managed" (ie ownership can be transferred) through other wallet software, but there's an important caveat in that transfers done this way will always "factory reset" (that is, unset keys & breach) the transferred ID.
It's about external software and unsupported usage pathways, so unsure if that's worth talking about on the site or not. But it's a footgun in a way, so that might push this into "mention it" territory.
