ECM is a rarely used module, because it's hard to use and often useless. It basically does the exact same thing as Point Defense, only manually activated.
The only place it could potentially be useful is on Small ships (or vs torpedoes, but that's so specialized it might as well not exist). Unfortunately, small ships are so limited on Utility slots, they really can't afford to take an ECM, and a Point Defense is going to be better anyway in most cases.
So, what if all small ships had an equally small, built-in ECM? It could be justified in that smaller ships, with smaller signatures, can use a smaller version of ECM, while larger ships need a utility-slot dedicated version.
This would make ships more durable against Homing Missiles, which are actually a decent threat against them, and will broadly encourage the use of ECM earlier in the game, which will lead to moderately more usage in the lategame, as well, since players will already have the prerequisite skill.
You could even do the same with some 4-utility ships, potentially, making hull tanks slightly more viable, which would be neat! Particularly the Federal ships, which currently see a mild lack of usage.
