This is extremely common in Universities where you share 2-4 public IPs that you can usually ask ports to be forwarded to a internal IP, and often there are resources (Like say Servers with GPUs) available on a interally reachable IPs using a easy to use hostname served by the internal DNS server. Ofc this change won't be that big of a issue, things would just need to change a little, using Split-DNS was already a pain when students wanted to say use DNS-over-HTTPS and didn't want the University DNS servers to know every site they visited.
