For reference, I've discovered a linux-netdev mailing-list article
describing this and an underlying change to the way the IFF_RUNNING flag
is used from March 2006.

[NET] core: add RFC2863 operstate
this patch adds a dormant flag to network devices, RFC2863 operstate derived
from these flags and possibility for userspace interaction. It allows drivers
to signal that a device is unusable for user traffic without disabling
queueing (and therefore the possibility for protocol establishment traffic to
flow) and a userspace supplicant (WPA, 802.1X) to mark a device unusable
without changes to the driver.
It is the result of our long discussion. However I must admit that it
represents what Jamal and I agreed on with compromises towards Krzysztof, but
Thomas and Krzysztof still disagree with some parts. Anyway I think it should
be applied.

So, on the face of it looks as if no user-space application should rely
on IFF_RUNNING.
