So yes, the ASes inserted in the AS-set are operated by others, and yes,
the announcements are sent out to the Internet at large.

This approach is highly questionable.  Any responsible ISP should kick
you off the net for announcing AS path containing ASNs without
permission from the real owner/assignee.

People have been prepending non-local ASNs onto covered routes as a crude inter-domain TE hammer for years. The sky has not fallen.
