It looks like an upgrade to 1.61.0 causes a build failure for MySQL:

-------------------------- BUILD OUTPUT LOG FOR MYSQL --------------------------
-- BOOST_VERSION_NUMBER is #define BOOST_VERSION 106100
CMake Warning at cmake/boost.cmake:266 (MESSAGE):
  Boost minor version found is 61 we need 60
Call Stack (most recent call first):
  CMakeLists.txt:455 (INCLUDE)


-- BOOST_INCLUDE_DIR /gnu/store/...fzzl-boost-1.61.0/include
-- LOCAL_BOOST_DIR 
-- LOCAL_BOOST_ZIP 
-- Could not find (the correct version of) boost.
-- MySQL currently requires boost_1_60_0

CMake Error at cmake/boost.cmake:81 (MESSAGE):
  You can download it with -DDOWNLOAD_BOOST=1 -DWITH_BOOST=<directory>
------------------------ END BUILD OUTPUT LOG FOR MYSQL ------------------------

So I guess the impact is too large to just go for it.

Do we have a Guix command to find out which packages are dependent on
a package (in this case Boost)?

Kind regards,
