The goal is not to maintain compatibility, the goal is to be able to
load the driver as a module on DT systems.  For historical reasons SPI
uses the platform device IDs to load modules bound with DT, if there is
no platform ID for a DT ID then userspace won't be able to find and load
the module.

The DT bindings are an ABI, you can't really remove compatibles only
deprecate them.

I2C doesn't have this issue with modaliases so it's not an issue there.
