Costs may mean not much in vanilla campaign, but they do in Nexelerin, where reputation is not a problem. Imaginos is more expensive than a Desdinova (one of absolute best player-ships, all mods included...), or several Mantis frigates.
Well, if you give the fluff some thought, why does it even exist? It's an experimental ship, mostly used for very specific combat scenarios, esoteric research, and technology testing. The Morpheus came later, and uses the same technology with higher potency, being a better combat ship in every way. If the campaign had more hooks, I would heavily gate access to it in a storyline (as well as its successor - perhaps even make the morph's existence a result of player actions, a la the Aurora Thunderforge in EVN.)
Since I cant do that, I decided to just make it fairly rare and very expensive to use, so that you'll only want to use it if you find it to be worth the hassle, so to speak. In the meantime, you are free to modify data in the .csv files to make it any cost and logistics stats that you want.
Speaking of this, future updates of BRDY will probably center on utility and low-tech ships - there's several "tech levels" inside the mod, with some ships like the Robberfly, Knight and Gonodactylus tending towards the low-tech end of the spectrum, and some ships like the Nevermore handling more like high-tech ships, and then the shieldless experimental vessels. I want to solidify the look and feel of the older vessels in the mod, and add some more sturdy, economic "anvil" ships to round out fleet choices and make the AI BRDY more interesting as an enemy.
