I must question whether all of these things work the way you think they do. Not all abilities transfer from components to facilities or vice versa, and MM has not clearly documented which ones do or do not.
The "Change Ground Defense" ability description in abilities.txt says it changes GROUND combat. Given how tough it is for troops to conquer a planet, maybe this is not a good idea right now.
But, yeah, the ability has been there for a while and MM has not got around to making a facility to use it. Same for Planetary Shields. There's nothing but the "artifact" technology. I have added both types of facilites to my custom techs.
The "Combat to Hit Dec" ability doesn't work with Weapons Platforms, just like multiplex tracking. In both cases the planet's attributes super-cede the units abilities. I doubt that either of these works with facilities either. Have you verified that this works somehow?
There is also no reason to think that adding research point generation to a component would work. I tried it a long time ago and it did NOT work. It is certainly possible that the game has been changed but there was never any announcement of this. Have you tested this and proved that giving a Medical Bay this ability actually produces any research points? Or that adding intelligence point generation to the various sensors really produces any intelligence points?
