Why should it be so great deal? It should allow me only to add filters on the traffic that is destined to me, not arbitrary filters...

Filters have a non-zero impact on cpu overhead. Where they end up in the forwarding path could negativly affect your upstream or other routers in a fashion that's signficantly worse than the attack on you affects them... The potential for someone at isp B to do engineering on the way that traffic from isp A's customers flow to isp B on isp A's routers ought to be fairly disturbing to most folks. Normally that's something that both parties have to agree on first.
