I guess I have the right wrenches, because I seem to take the bracket off about half the time anyway.

Yeah, getting the pump and bracket off certainly is not impossible, just irritating since there's a lot of stuff for your wrench to run into... I also have never met one that couldn't be removed, but I got tired enough of fighting that battle that I finally got the skinny puller tool for yanking the sprocket off with pump in car.
I think the part that sucks isn't so much getting the pump off, but getting it back on the motor with it still mounted to bracket -- trying to get the two upper bolts started with the pump body right in the way, and then you have to go thru the whole belt tension routine which takes a few tries unless you get really lucky. I much prefer pulling pump on its own then being able to just drop it back in and have everything go back the way it was before... (edit: saves having to mess with the glow plug buss too!)
Slightly different tension wouldn't appreciably affect timing -- I think I experimented with it once and loosening belt meant slightly more advance, tightening a little less advance, but the differences were minute, ~.01mm or thereabouts.
