When I've got tabs to remove I'll bandsaw through the tabs, then flush trim what is left over at the router table. The spiral upcut pattern bit typically leaves no trace of where the tabs were.
Oh, trust me, I have used the band saw and the router table. It is really tricky band sawing interior cutouts though. I haven't figured out that one yet.
Just an aside, years ago I read something by, I think it was David Pyel, who discussed something he called "the craftsmanship of certainty vs the craftsmanship of risk". Here is a link that contains what he discussed:http://promotingprimitivism.blogspot.com/2014/01/the-workmanship-of-risk-vs-workmanship.html
Essentially what I am practicing is craftsmanship of certainty. With everything locked down I know exactly what the result will be. It will also be repeatable part after part. Once the part is removed from the machine and a person starts manually handling it through other machines a certain element of risk enters the picture. Slip on the bandsaw and a ding appears on the edge of the workpiece. A void on the edge of the part will cause the flush trim bit to cut deeper.
I don't think everything needs to be made that way, I do a lot of stuff manually with a certain amount of risk involved. But since I am using a computer controlled machine I see no reason to add risk and more time when making a part on it.
All that said, when I need edge radii you can bet that I do it on the router table because it is faster to set that up than to do it on the cnc. And when the parts needs the edges on both faces rounded, it becomes obvious the router table is the better method.
