That makes you a bad upstream operator, one that does things without understanding the consequences. This may still be the unfortunate norm, but it's by no means something to be considered an acceptable state.

Put otherwise : if you have downstream customers that you allow to announce part of your address space in the GRT, make sure you can still provide the service after doing changes (like RPKI signing).

Put in a yet another way : if you lease IP space (with or without connectivity), make sure all the additional services are included in a way or another. Those services should include RPKI signing and reverse DNS, and the strict minimum (only slightly better than not doing it at all) should be via "open a service ticket"; the more automated the better.
