The original Lords now specify "other" and Goblin Rock Sled is now Goblin-type. The burn spells had to specify that they work on both Creatures and players. Back then it was probably much more difficult to work out.
You missed the point. I play with a
4th edition Lord of Atlantis in my Kumena deck and having to explain that he is, in fact, a Merfolk that can be tapped for Kumena's abilities, benefits from other lord effects, etc. but, as a result, his actual oracle text is "
Other Merfolk get +1/+1 and have islandwalk," not "
All Merfolk get +1/+1 and have islandwalk," is annoying. Especially when I play against people I don't really know and they pull out their phone to check Scryfall and make sure I'm not messing with them.
Our point is: when they make functional errata, it's annoying for players with older versions of cards with the outdated text to have to
relearn what the card
actually says, let alone use it in a game against other players who may think that what is printed on the card is what the card does.
