This is intended. You can find a crucible earlier, or get one from another player or trader, and still craft steel without level 5.
Yeah; this. You can craft steel from the start of the game, the only thing preventing you from doing so is whether or not you have a crucible, which can be acquired from a number of different sources. One of those sources happens to be rank 5 of advanced engineering- But that is NOT the only way to get it.
Further, the +25% steel/electrical crafting speed is NOT the primary effect of the perk, but a secondary effect. The primary effect is the exp gain from electrical traps and the teaching of the recipes.
Much of the skill trees, book, and loot systems is about providing multiple paths to the same goal; You can learn the recipe from a book, or get it from your skill tree, or find the item in world, or buy it or the recipe from the trader.
