Very true, as application-layer load-balancing often explicitly pre-bakes the traffic schedule to several hundred distributed IPs for data locality. Essentially bypassing the functional need for DNS and local round-robin traffic balancers.
One trades concurrent bandwidth for slightly higher latency, and dynamically adapted capacity as traffic load changes. =3
If your clients are all this well behaved, then you’re definitely not exposed to the public internet.
The global edge networks that I’m aware of all use L4 LBs and L7 LBs. Cloudflare picks anycast over DNS LB, but DNS LB is still widely used.
I don’t see these things changing.

Time Division Multiplexing is usually already used on cellular and Wifi wireless protocols. It only requires slight modification to turn it into an effective network traffic balancer to avoid the naive "everyone update on Tuesday 6am UTC", or "It is Christmas morning and game registration is open".
Notably, it also allows tracking specific accounts by encoding disjoint ingress host lists (siloed concurrent user groups with client certs and firewall whitelist rules.) And users do not have global network knowledge as hosts are cycled into temporary stewardship under load. Thus, only the coordinators for one-time new-user registration operates on classical DNS/round-robin host services.
With DNS, by expected function everyone knows the global published ingress points within minutes. Under a DoS the traffic just hammers down, and small firms usually just pay for the Cloudflare like services.
For systems I've known, TDM reduced peak resource capacity costs down by around 37x. Generally speaking, a 100 user group having fun will not share their server details/invites with folks that exhibit lag-switching or other network shenanigans.
But you are correct, in that it doesn't help if PIBKAC. =3
We're definitely talking about different things. The open internet is hostile and you'll always need load shedding when the clients misbehave.
If you control all clients and servers and are on a closed network, you can do all sorts of fun things... though load shedding is helpful for when your good clients turn bad due to a code bug. A self DoS is the worst kind of outage.
