Alas that makes no sense?
You might not agree with it but it does make sense.
The Engineers are not suppose to give you a "win", but an alternative, hopefully more suited to your play style.
If there is a suggestion that certain crafting/enhancements are significantly better (rather than just different), I'd suggest it's only going to make the game worse.
As opposed to a fully A kitted ship versus a fresh off the shipyard production line? Elite is not about balance, it's about choice. Engineers will just give more of it without allowing everybody to instantly jump on the latest over powered build and bear in mind that just because somebody has an engineered module does not make it better, there are downsides and compromises have to be taken in 90% of cases.
And if you're right, and new metas pop up that module X crafted with Y is the new "must have", (eg: previously rail guns on silent running craft), then why only allow individuals who have the will power to grind to have access to them?
So it doesn't become Elite : Meta 2.1 #moduleftw!!1 and become dull as dishwater, how is that not obvious?
Far better to let people have (failrly) easy access to what are hopefully fun variations to weapons, and let people enjoy using them, than simply forcing people to go through hours and hours of grind for each and every thing they want to play with.
Who is forcing it on you? Nobody but yourself. Hours and hours? based on what? You're making assumptions on outdated information, nobody knows as it stands how long or how much effort is required as it was tweaked and removed after the initial phase of beta.
