The thing is, speculation can take many forms. There's the whole area of speculation that's based around finding novel applications for the existing capabilities within the framework we know of, and there's "but what if this fundamental constraint doesn't exist" speculation.
One of those leads to interesting discussions (such as, what's the minimum viable size for a CLAC? What can Manticore do to ensure its tech superiority in the future?). The other leads to "but what if we could fire missiles through hyperspace" or "we can detect spider drive ships by building a giant sphere of satellites shooting lasers at each other". The latter is inherently pointless, because once you start throwing out the constraints, what's the limit? Like, we could just as well start talking about the combat potential of a 100 mton ship with a magic compensator that allows it to pull 800g of accel. Or what would happen if we could put SD-scale grasers on dispatch boats. Or what the potential applications of a Keyhole-equipped Destroyer are. Once you throw out constraints, discussions about what-ifs become meaningless.
And that's the mistake Skimper makes, constantly. For him, constraints do not exist. There is no limit to what he thinks can be done in the Honorverse. As a result, his designs and daydreams are rubbish, because he's essentially using authorial fiat to declare everything he comes up with as the best thing ever.
