Perhaps it's not, but it's certainly far less likely to cause a restore
failure than the behavior I want to replace.

More to the current point perhaps, I doubt that it's likely enough to
cause a restore failure to justify the existing docs warning.  There
may have been a time when the warning was justified, but I don't believe
it today.
