while presence of the library will almost certainly not change during the
lifetime of Chrome, is it possible that the machine's registration with MDM may?

[Roger Tawa OOO till Jul 10th, 2017/02/13 20:30:06]

Let me double check.  A larger question is whether chrome is capable of handling
that at runtime.  Today chrome assumes it won't change.
