Hi Meir,

The issues are mainly historical at this point.

   - Limited some of our options when looking at global zone distribution
   partners.
   - Very old resolver code that just did not handle it well, this has
   faded with time.
   - Some issues with CA's and certificates, this also not so much of an
   issue anymore.
   - Managing the domains/zones in some services like Cloudflare/AWS not
   recognizing it properly, again mostly ok these days.
