In general it is used for specifying the CA of a certificate used on SSL websites. Modern SSL validators (i.e. https://dev.ssllabs.com/ssltest/) will look for CAA records. Especially with Let's Encrypt it became extremely easy to host SSL websites nowadays.
It is not very urgent or important, but since almost all DNS types are supported by time4vps, I thought I'd mention it here. I don't know how hard it would be to get it working.

Thank you for great suggestion. However, could you please provide a practical adaptation of this feature? How would you use it?

There is an example here for BIND: https://community.letsencrypt.org/t/caa-setup-for-lets-encrypt/9893/17
