I'd still advocate for making the change, since especially with the additions of static variants and runtime detection, it becomes easier from within a booted kernel to identify the type and version of U-Boot image installed. Without making this change, it becomes less direct to determine an actual Pro vs. Base, vs old U-Boot image maybe supporting some hybrid variant configuration. Even in the Linux kernel adding of the Pro DTS, it is indicated that it was meant for backwards compatibility. Except for cases where checking is done directly against the product name from userspace, I don't see downsides even from a compatibility perspective for not making this change. In cases where checking *is* done from userspace, the broadening of the Clearfog product line would seem to mean that userspace checking should be flagged as needing to be udpated as well (or glob/regex matched as needed).
