On older LEDs you could replace the caps, but newer ones use SMT caps that require more than just a soldering iron. It makes a huge difference, and also eliminates the slight delay when switching the lamp on (though I don't recall experiencing this with recent LED lamps, even cheap ones).

  searched for images of "LED bulb teardown", the SMT components are not that tiny, so quite possible to solder with a regular iron. Am I missing something?

    Really the worst part is that the bulbs are usually glued/ultrasonice welded, together, so you kind of have to destroy it to open it up.

      You can cut them open with box cutters. You don't even have to glue them shut, just cut 270° and seal with electrical tape after. Ali Express has white electrical tape if you prefer.

  I really hate modern technology sometimes. I have nothing against being more energy efficient, running cooler, lasting longer, but we're losing some great things along the road. I have to pay 3x the price for a CRI>90 LED w.r.t. a CRI>80 one. At least the price difference brings better light quality regardless of CRI (soft start, dimmability, even less flicker, better light distribution). On the other hand, I'm happy that I can get halogen bulbs if I really want to. The problem comes from losing past frames of reference. We say "we're at 99% of benefit parity with the previous generation", but this 1% losses compensate every generation, and now we live in a more efficient, but arguably less comfortable life.

    I would rather buy a incandescent light (even if I have to pay 3x or 5x) which is not as bright as the LED (forty watts or possibly even lower, should be sufficient; I have a few 40W incandescent light and they are good enough), and then not turn it on in the day time when it is light outside. (Unfortunately, other people where I live like to turn on the light even in the day time and that bothers me.)

      You can buy an E27 halogen bulb around 50 watts (which would be around 100W incandescent) and pair it with a universal dimmer. It'd provide you nice warm light, and will allow to flood the space with bright light if the need arises. Neither of them are expensive. Halogen bulbs are also CRI100, so their color rendering is not different from incandescent bulbs. Turning on lights when you have ample sun is not a wise choice, I agree.
