I have a drawer full of black electrical tape and small round dot stickers almost entirely due to blue leds. Though it's convenient on everything. The electrical tape blocks it out entirely, for the most part. The round stickers let through some light so is great for dimming it down a bit or just use multiple to block it completely.

I think they're so widespread now largely because they were so expensive when they first started becoming common that they were used in expensive equipment, and became a way of making things look higher end.

I’ve found that for many of them (particularly the smaller ones) I can color them in with a black pen in a way that dims them ~95%, that way they’re not overbearing but I can still see whatever status they were trying to tell me.

Ballpoints or other fine-tips tend to follow the shape of the recess and it does a pretty tidy job.
