It seems right the suggestion from the compiler, since from ICU release 67.1 the API changed: https://unicode-org.github.io/icu-docs/apidoc/released/icu4c/classicu_1_1number_1_1FormattedNumber.html Since I have installed dev-libs/icu-67.1 from my personal profile, ebuild needs correction for icu required version that should be below 66.
In Arch Linux I see they manage to use ICU 67 applying the following patch https://git.archlinux.org/svntogit/packages.git/tree/trunk/icu67.patch?h=packages/chromium
