I'm OK with sticking with the <2.27 binutils behavior. The gzip data is:

binutils 2.25:
Image 41467904
Image.gz 13395151
binutils 2.27:
Image 41467392
Image.gz 14114953

gzipped kernel increased by 0.69 MiB.

The one special case I see is !CONFIG_RELOCATABLE and compression is
used, where there's a tradeoff between compressed image size and the
benefit of dynamic relocs.
