Adding another vote here, we previously relied on Google Domains which kept everything secure within our internal workspace and allowed for easy ACL management.
With the shutdown and migration to Squarespace (which we don’t use for anything else), the ACL limitations make it hard to manage as a company numerous domains centrally. They even require you to upgrade to a paid plan if you want to add more than 2 users to help manage domains. We already use Cloudflare for nameservers on most of them, and having them natively in Cloudflare would be a much better end-user & I.T. experience.
Unfortunately, since cloudflare does not support .co.nz we are unable to migrate some of ours until this is added.
