In addition to what Linus already said: I think this is a good moment
to get rid of the platform data structure and instead use device
properties, what do you think?

If you're thinking of fwnode that will not work with static platform devices
(such as add with board files or other random platform_device_register() etc)
The fwnode concept only works with DT and ACPI.

I was thinking about using generic device properties: add property
entries with platform_device_add_properties() and read them with
device_property_read_*() functions. Is there any reason this wouldn't
work?
