I have a Brother printer from 2019 (HL 2340) that does not support IPP Everywhere. A lot of other printers from before ~2020 don’t either.

You are (like so many other people) confusing IPP the protocol with IPP the driver, which is honestly not your fault and a terrible naming mistake.

And like you mentioned, people have way older printers because if all you do is print monochrome and mostly text, a printer from 2004 doesn’t lack much aside from AirPrint / Mopria. Which is why I suspect CUPS will not deprecate at least PPD drivers.

If you read the linked issue you will see that the plan for legacy printers is to move the printer drivers under a separate application that CUPS can then talk IPP to.

So yes, CUPS itself will only support IPP without any printer-specific driver. Since mobile phones also only directly support IPP this sounds like a reasonable decision.

Ah, yes. Thanks for pointing that out! I wonder how much more secure that will make things for those who have to use legacy printers.

Technically AirPrint is not IPP Everywhere, they use a different raster format and some different glue. For example my Brother printer supports AirPrint but fails ~50% of the IPP Everywhere self-certification tests. But that’s splitting hairs.
