I am sure this does not apply to a home workshop and might be why commercial shops use spindles and not router tables. Also the larger mass of the spindle head will keep going compared to the router cutter.
When thinking about safety I believe it is not a good practice to say this machine is more or less dangerous than any other machine, you should just think all machinery has the potential to inflict injury and should be treated the same. In some ways the insignificant looking 1/4 chisel on your workbench can be lethal and cause life threatening injury so lets not differentiate safety levels.
The fact you have to take multiple passes on the router is a good point as you are just multiplying the time you are at risk from the hazzard and also often with smaller workpieces, at this rate I will have talked myself into a spindle moulder rather than the router table upgrade.
