DHCP with a /23
I switched my orbi subnet mask to 255.255.254.0 in order to gain more usable addresses, however the DHCP settings hard code the first three octets and won't allow me to use more than 253 addresses. A...

I know for a fact that TP-link XE75 and BE85 (there may be more models, the XE75 did not work very well for me) use a subnet mask of 22 bits and the DHCP server works fine with my 100 or so devices which is more than I can say for the Orbi.

I was talking about Netgear devices only. The point is not the limited subnet size, the key point are the resources like storage and dynamic memory required to properly support to support 1024 devices in every aspect - which is more required than just allowing the LAN and the DHCP server to be configured to a /22. Other aspects in the design must be considered and properly covered. For reasons, the vendors carry notes like "Connects up to 200 Devices†". And no, this is not about the limitations in the WiFi subsystem. Re-think how useful a /22 subnet configured can be in reality - misleading at most.
Also the fact that Home class systems are designed in mind for house holds with mostly less than 100 devices on average. So the FW and system are typically developed for these home environments with say a max of 200 devices. I have yet to know someone personally with 200 devices connected to any Orbi system or any home class router for that matter. Most I've heard and seen is 80-100. I think someone posted having just over 100 but don't remember where or whom. I know one friend who had around 80 at one point a while ago but he's since has a few less now days. Over all, if users need or want a router that and subnet and do more than what most NG home class routers can offer, you'll need to find a different system that does. You'll only get what you see for home environments from NGs home class products. They were never meant to do more beyond that.
