I think if someone has Facebook account they will use it, me too, I'm curious how would it look like. However, it hasn't been launched yet so it's hard to say, it could turn out that Libra is completely unworthy of attention.
The chances of Libra getting released anytime soon looks very remote. From what I can infer from Mark Zuckerberg's recent statements, it looks like he is looking for a honorable exit. The technology and complexities associated with cryptocurrency was more difficult than he ever imagined and as a result he has decided to pause the project and move on with other priorities.
It might be true, some time ago I heard that Libra is in question because they don't have enough experience and knowledge to launch it easily. It will be much better for them if they stay focus on their priorities just like you said
