Do you pay attention to fabric composition labels when donating or recycling clothes?

Random thought while cleaning out my wardrobe:

When clothes get donated or recycled, the fabric label is often the only real info attached to them. But labels fade, get cut off, or just disappear over time.

Do you personally care about keeping that fabric composition info, or does it not really matter once you’re done with the item?

Would saving it somewhere before donating/recycling feel useful, or would it feel like too much effort?
