What’s special is that they are inherently visual instead of symbolic. What happens when the culture shifts and :bug: is replaced by :pile-of-shit: ? We now must remember that 5 years ago, we used :bug: to mean software defect but after that one blog post we all use :pile-of-shit:?

If you mean that performance improved just write PERF instead of :lightning-bolt:
