The 16.5.0 package released to unpkg currently has the production/profiling variant present for cjs builds but there is no equivalent for umd builds. 

i.e. There is the file https://unpkg.com/react@16.5.0/cjs/react.profiling.min.js but there is no https://unpkg.com/react@16.5.0/umd/react.profiling.min.js

It would be great if a future release had the profiling variant packaged as umd as well.

Also thanks for the awesome framework!
