I can see how it's a way of allowing some tags like bold and italic without needing a library or some custom parser, but I didn't understand what the point of this default could be and so why it exists (a sibling comment proposed a plausible answer: hardening on top of another solution)

"don't use it if it's not what you want" is perhaps the silliest possible answer to the question "what's the use-case for this"
