How good is the idea to make the domain delimited?

Question

Domain Name System

Actually, a simple question, but I want reasoned answers.
There is a client who proposed to create a site domain of the form "repair.apartments.in.tambov.rf" ( dot separator )
I.e. "tambove.rf" is registered, the rest is through third-level subdomains.
The site will be advertised in Direct, a purely advertising landing page.
How is this option worse or better than the "repair-of-apartments-in-tambov.rf" option?

Answer 1

if he makes repairs like God .. I don’t care how to score)))

Answer 2

it's not gonna go. a point in a third-level domain is not allowed. I remember it was easier to get rid of it than to fight for it to work. and according to the standard it is impossible
The Internet standards (Requests for Comments) for protocols mandate that component hostname labels may contain only the ASCII letters 'a' through 'z' (in a case-insensitive manner), the digits '0' through '9 ', and the minus sign ('-'). The original specification of hostnames in RFC 952

Answer 3

Shitty idea no one will enter such a domain manually, you will kill all direct traffic
