> In practice URLs often cannot be more than 2K characters. It's also more work to type and bytes to transmit and harder to see on small screens.
The longest vanity TLD I could find was .travelersinsurance. Two dozen characters are nothing more than a rounding error in the 2k character limit. You routinely pass 10 times more characters in path and query parameters than you do in the domain name.
Also, how often do people type in URLs instead of clicking links?
Also, keep in mind that some browsers are starting to hide path and query parameters in the address bar and instead only show the domain name. I presume that makes domain names and TLDs more relevant in terms of name recognition.
