That and we can't add this unconditionally. This is a shared ASL file. […]
Yes, the plan is to generate this stuff at runtime. In fact, https://review.coreboot.org/cgit/coreboot.git/tree/src/ec/google/chromeec/ec... already takes care of generating the connector nodes with _DSD in SSDT.
However, there is still more work required to be done here.
