Klingons never really get past the 'Using weapons that mostly just look cool' thing if the Bat'leth is any indication.
funny enough, while it's not a particularly practical weapon, it's also not spectacularly IMpractical...untiil you get to Discovery's version, which has exactly NO way to hold and wield it without pointing it
at yourself.
which is kind of a fatal mistake there, shown in the first encounter burny has with a Klingork, she bumps it into him-and through him...
by accident.
Take a look at "Disruptor pistols" from TOS, TNG, etc. vs. the "Disruptor pistols" from Discovery, which kinda look like bronze rings with spiky bits attached, rather than the relatively ergonomic (four fingers and a thumb hold them easily-which even discovery's klingorks possess), angled-grip-with-a-long barrel (which is good for lining up aimed shots, btw). The spiky bits on Discovery's weapons serve no purpose-they aren't good for knuckle-dusters, nor good for carrying where you'd carry a pistol when you're not using it. (I really have to wonder about that, it doesn't really 'holster' well, and it's an awkward draw for something with hands and arms shaped like a Discovery Klingon's hands and arms...)
Then we can go look at their 'warrior dagger' designs, from ST3, through DS9, to Discovery. in the prior examples, they're made of metal (both types,) ahd have spring-out sharpened guards (both types.)
However, the grip on the Discovery Klingork weapon is going to be real interesting to try and hold on to as soon as it gets wet with...like...the blood of an enemy? (Slick metal surfaces with scaling laid out to make it slide out of your hand isn't good grip design in ANY culture, if you're going ot use scaling, it needs to either encourage grip or be neutral, and not be angled to make it easier to drop.)
and then, there's the armor...
yes, it's pretty, isn't it? and you can't move around in it, your radius of motion on your limbs is restricted, it's layered to helpfully guide enemy fire and weapons into your vital organs. it is functionally the OPPOSITE of what armor should do, and that's just looking at the general SHAPE.
I mean, the shape and crafting practically announce "If you wear this into a fight, you will indeed, die in battle." and that might be glorious, but nothing is more honorable or glorious than
Winning. (and you don't do that dying) which is why DS9 Klingons wear armor and uniforms that provide coverage of vitals, and enable
fast, athletic movement, so that you can....y'know,
win fights occasionally?
I mean, come on, in the fight scene in episode 3, Michelle Yeoh's character had to practically
help T'kuvma stab her. (either t hat, or she decided to play a person with zero situational awareness and mild mental deficiency either way, it was a fight scene even LESS exciting than watching Jim Kirk apply the two-handed slam-punch..).
Basically, the full Klingork Retcon is taking a faction that was "Worthy Adversaries" and making them "Incompetent buffoons."
which, I guess, is what the modern market was clamoring for...but it demonstrates a defined effort to ignore or remove continuity, and my point stands-if the showrunners decide to keep the Spore Drive, nothing is going to stop them from simply determining that it's in for the rest of the run and all sequels.
Because, y'know,
they own the IP and can do with it what they want...and that includes declaring the new to be 'continuous' with the old even when it blatantly isn't.
