Who "paints the red line"?

I had the Bosch 4100, it had a little circle indent in the table top ahead of the blade where they put a paper sticker that you can mark with a pencil where the blade cut line is – more to help align cuts before it contacts the blade. it does sounds like a good safety procedure.

-- When in doubt - There is no doubt - Go the safer route.

Most blade-surround inserts are bright colors to warn of proximity to the blade.

As far as alignment goes, I use the kerf in my sled or sacrificial miter guage fence to judge alignment.

Bt 3000 came with a red line.

Later Emerson saws (Sears, Ridgid, ???) all had a little plastic circle insert in the cast-iron tables before the blade. I think it was called “Exacti-cut”. That was its whole purpose in life; scribe a line (or two for the thickness of the blade) and you knew exactly where the cut was going to be.

-- "Find out what you cannot do and then go do it!"

Maybe I’m missing something here. Personally, if I need a thin red line to tell me I’m too close to the blade with my thumb—-I’m too close to the blade! I am a strong believer in safety, and still have all ten fingers, and expect to keep them.
However, if you’re using it for alignment, then it’s a different issue. Maybe it would be a good tool.

Here’s why the red line: The Ryobi BT3 saws and some of their Craftsman cousin and the BT21 have the infinately adjustable miter bar on a sliding table instead of the usual miter gauge riding in a track. It is easy to slide the miter bar too far to the right when switching cut angles or setting it up after doing a lot of ripping. Usually your first indication that you’ve got the bar too far to the right will be seeing bits of black plastic in with your sawdust as you watch the cut—where did they come from??? You’ve just sawed off part of the plastic “ear” on the right edge of the miter bar. The red line is useful to remind you to check the location of the edge of the miter bar on a Ryobi when you line up your cut.
