Do you confirm that this ABI change doesn't effect the other reverse 
build dependencies of src:swi-prolog? If that's the case I'm fine with 
removing the block. But I'm afraid (without checking from my side) that 
the other package don't have the right virtual ABI package in their 
dependencies. If they do, wouldn't they need a rebuild too?

Also, if logol is already doing the right thing, shouldn't you as the 
uploader of swi-prolog request a binNMU for logol to enable your package 
to migrate at all? I mean, I would expect the migration to become 
blocked by uninstallability of logol in testing without a rebuild.
