I don't think it's fair to expect the EU to bend over backwards to accommodate the defectors after how they behaved. The UK knew what would happen and they choose that path anyway throwing a large number of UK citizens under the bus. It's unfortunate that they made that choice, but it's not the fault of the EU and it's not the EU's responsibility.
It also seems a bit unfair to suggest that .eu domains aren't dependable as if the same thing could happen without warning to any member country considering that the precedent established is that it would only happen to countries that insist on it happening to them.

The politicians definitely all know it wouid be a disaster - Gove and Johnson's faces on the day of the result look like they're at a funeral.
The public, however, insisted that "we knew what we was voting for", verbally abusing anyone who asked them what that actually was, and now are claiming that "this isn't what we voted for". Well, it was, and you were told so. Let me play the world's smallest violin in sympathy.
In addition: after the referendum, the EU offered all kinds of options to make it a soft Brexit, but those same politicians drew unnecessarily strong red lines (and are still doing so regarding Northern Ireland) in order to appease a tiny extremist minority in their party. There's only so much the EU can do. Decisions have consequences, and I can't blame the EU for being a bit too strict now and then in response to that kind of game-playing and plain incompetence.
