From the point of view of a newly created colony of opposite-handed bacteria, it would be facing an entire planet of really well established mirror life.
Mirror species can eat the local species, so they have it easy.
Mirror life can only use the fats and a few amino acids of the normal life. All sugars have chirality so they would need some enzymes to east their own mirrored sugars and another set of enzymes to eat normal sugars. Also, most amino acids have chirality and they would have to reverse them or make their own.
So even if someone waste a few gazillions dollars to make mirror life, it would not be able to eat most normal food.

Until mirrored life evolves enzymes to eat non-mirrored sugars, mirrored life will be at a large disadvantage.
But with exposure to our environment, replete with non-mirrored sugars, that sets up a large evolutionary pressure in the direction of finding those enzymes, in addition to the mirrored enzymes they will already have for eating mirrored sugars.
With such evolutionary pressure, it seems plausible mirrored life will evolve those enzymes, even though non-mirrored life appears not to have done so, or at least not retained it. Because there has been no equivalent evolutionary pressure for non-mirrored life to eat mirrored sugars.
If mirrored life does evolve those enzymes, due to that asymmetric evolutionary pressure, then instead of being at a disadvantage, it might give them a temporary advantage over non-mirrored life.

Until mirrored life evolves enzymes to eat non-mirrored sugars, mirrored life will be at a large disadvantage.
But with exposure to our environment, replete with non-mirrored sugars, that sets up strong evolutionary pressure in the direction of finding those enzymes, in addition to the mirrored enzymes they will already have for eating mirrored sugars.

If mirrored life does evolve those enzymes, due to that asymmetric evolutionary pressure, then instead of being at a disadvantage, the ability to eat both types of sugars might give them a temporary advantage.
There were large extinction events, prob most notable from this was the great oxygenation event that wiped out most anaerobic life. Other than that I can think of stuff like fungi evolving to break down cell walls.
It does actually, because it implies it fought and lost that battle the first time.
Now, with L-amino life everywhere it would have an even bigger starting problem.
We see this with extremophiles: organisms which can grow in nuclear cooling ponds full extremely badly when transplanted to nutrient rich environments with other, less capable organisms.

Depends what you mean by worse: ink is a big problem for recycling paper (along polymer-filmed "papers"). Thermal ink isn’t an exception and contrary to other printer types, it need to cover the whole page for the printer to work.
I don’t think it’s a major health problem if you don’t consume your daily newspaper after reading.
this seems like an absolutely terrible idea! I thought this was going to be about editing gaussian splats, which is sorely needed. instead, it's about turning a few pixels into a gaussian splat in order to edit them?! My god, talk about using a nuclear bomb to kill a fly!
Thanks.
