I meant “usability” in the software engineering sense in https://en.wikipedia.org/wiki/Usability

Usability isn’t a binary “usable” vs. “unusable”. Rather, usability can vary by the task at hand and the user performing the task.

At least, that’s why I suggested “likely usability” and “among their target audience”.

 

The reason for emphasizing transcription is not that there aren’t other operations that are possibly more frequent (copy/paste a URL from one context to another, remember on a bookmark list) but rather that transcription is the most stringent requirement – if a user can transcribe a name resulting in the same sequence of Unicode codepoints, then they can display the name, distinguish the name from other (transcribable) names.

Registries should be conservative in the sense of advising their clients

about the likely usability of the registered name among their target
audience.

They simply should prohibit unusable sequences.
