I can't see that this is a bug per se, as the behaviour has never been intended. You can't buy a subdomain at a registrar, and this is intended to be used to register domains with registrars.

Can you explain the use case for this request?

When ordering / providing your own domain name it should not be an issue

@Anuril My concern is that clients cannot use a subdomain for Servicehosting

[cztk]

a good system should not struggle with this.
If I sell cheap or even free webhosting with the option to remove ads or the client actually does not need a domain
or is going to add it later if the hosting panel allows.
Or maybe just some fun project where you make everyone use a special dns for, well ok but the point is, hosting with subdomain is a very valid thing.
In general I can't see why ordering a domain and webhosting package is in any way related enough really, it should not be dependant on each other.

Edit: Rereading the original post, I got mislead in my thinking - yet still is a valid reason why a customer may chose to host only a part of his domain with some company. Imagine someone providing white-label service and the easiest way would be to offer them incrediblewhitelabel.domain.com

Another reason might be technicality, a customer having a heavy load on img. forum. or whatever .domain and for some reason, as you want to host on another server, panel even maybe, a 2nd account is needed.

Whatever, boils down to it should be:
domain valid y|n
and foo.bar.ene.mene.planche.est.info would be correct and should be accepted.

The same problem. Invalid SLD when I supply domain .domain.com as a client. Is there any solution?
