Granted, but if that's the concern, that's what the article ought to be explaining: We are aware of the infrastructure to break 1024-bit discrete logs, and it's feasible; current projections put 2048 bit key safely out of reach for the time being, so we'll disable 1024 and leave 2048 enabled. My concern there is with the talk of 'unknown attacks' and then providing suggestions based on that statement.
