Wildcard option with TLDs

[cyrilwanner]

It looks like the wildcard option cannot be used together with the topLevel option.

const isValidDomain = require('is-valid-domain')

isValidDomain('ch', {topLevel: true, subdomain: true})  // -> true
isValidDomain('*.ch', {topLevel: true, wildcard: true, subdomain: true})  // -> false

// one from sldMap.json has the same problem:
isValidDomain('gov.sg', {topLevel: true, subdomain: true})  // -> true
isValidDomain('*.gov.sg', {topLevel: true, wildcard: true, subdomain: true})  // -> false

Is this a bug or something that can be supported in the future? Either with those options or a new specific one (e.g. secondLevelWildcard)?
Thank you already for your feedback!
