This is simply a researched version of the passive bonuses to unit creation speed in various alliances, save for being centered on the castle. Whether the Britons with Archery Ranges, the Celts with Siege Workships, the Goths with Barracks or the Huns with Stables, passive bonuses like this do exist. More focused ones exist as well, notably the Turkish bonus to Gunpowder unit creation speed. The rate is probably slightly higher (25% vs 20%) due to the fact that this is not passive, but a researched tech.

Although this tech was broken and OP when one had multiple bonus's stack, after that was adressed, it is a slightly improved version of those passive alliance bonuses. It is very beneficial for anyone who seeks to use their civ's unique unit in large quantities, minus the Goths and Huns (due to being able to train their UUs at the Barracks and Stable respectivly) and or who wish to create lots of trebs.
