The process that is actually being suggested here (and towards which the 
implementation is heading) is that in case of the convergence being stuck 
for unknown reason, the admin of the system collects all the necessary 
data (namely stacktraces of the relevant tasks), and requests a clearance 
from the livepatch distributor to force the transition.

But I agree with you that this might not be completely clear from the 
documentation, and should be made more explicit.

Thanks,
