Boost-regex depends on ICU, and re-exports ICU symbols making its ABI
dependent on ICU ABI.

In Ubuntu we split publish boost. Up until 2016, there were packages in
"main" section that used boost-regex, since 2018 there are none - meaning
either stuff switched to std::regex or got demoted from "main" for other
reasons. I think it does line up with Ubuntu defaulting to c++11.

If boost-regex is better, should Ubuntu switch to it as the default
std::regex provider? Such that anything built on or for Ubuntu uses the
faster implementation?
