Hmm, be careful with an icon textures. I see no problem with those two packages because there is no other alternative (well except vanilla emote no-icons and who would want that?) but if there were it might be a big issue. See the discussion and resistance over the great TAD's colored spell icons v2 I added into CPP. But my project is low-level and you can easily override that. Including icon overrides into haks is generally a bad idea because there is no easy way to override them for a usual user. Plus, icons are client content, while haks are both server and client, meaning lets say I am doing a module with Q - and I as a module author will not want these icons. So I remove them from my haks thinking its all ok. But its not! because a Q, same like CEP is a hak that players are dowloading from official source and this hak will have those icons. In other words - removing from hak is not a way if I as a module author want my players see different icons. The only way to do that would be to add a new hak with icons I want players to see, however my choice might not be a choice of a plenty of other players again .
Side note just in case you missed that '> : both these icon overrides are included in my CPP project (1.70: effects, 1.71: emotes, more effects).
Just a suggestion, as I said already for these two, there are no other choices anyway.
