I live on the edge of the FAA Warning Area for GPS testing in Nevada.
There have been instanes of GPS loss here due to testing.

There was a space storm a few weeks ago, mentioned in time-nuts.  Many
people, including myself, lost GPS time because of it.

Then of course you have start up transients.

Yes, probaably minor annoyances, but why not do it the best possible?
Just a config change.
