The only (possible) downside to this suggestion is that it will probably make unmasking of the merit sources easier.
Theymos didn't want to publish the list, because it could result in them being pestered for merits...
Theymos also said:
If you pay attention, you'll get a pretty clear idea of who the active sources are
and that is true with or without third-party scripts. Mainly, you'll just have to
check this in a few months and you'll have a good idea of the list.
So I don't think this suggestion will make a difference on that matter. It will help identifying other things much harder to spot only with the currently available tools, such as abuse and advanced stats.
