This package is unused, and was causing problems with installing babel. Because
it dependended on an older version of babel, and was interpreted by npm first
(as it is a regular dep), the older version of babel would be "hoisted" to the
top level of node_modules
Then when latest versions of babel are installed they would be interpreted second
and thus would nest their dependencies within their own node_modules, filling the
disk with unnecessary copies of core-js.
Removing the unnecessary dep solves these problems
