Is it hard to get listed on KuCoin?

As a keen observer of the cryptocurrency landscape, I'm curious about the process of getting listed on KuCoin, one of the leading cryptocurrency exchanges. Could you elaborate on the challenges involved in achieving this feat? I understand that the platform has strict listing requirements, but I'm wondering if these pose significant barriers for projects seeking exposure. Would you say that the vetting process is rigorous or reasonable? Are there any specific criteria that projects tend to struggle with the most? Your insights would be greatly appreciated in helping me understand the intricacies of this listing process.
