Honestly explicit sarcasm indication should just die out entirely. Might as well be writing it longhand as "Just in case you missed it, this is a joke haha." every time you tell a joke.

I’m not sure if you’re being serious or not. I’ve never met you and tone isn’t conveyed over text.

I’m assuming you’re joking, but maybe that’s exactly why we need explicit sarcasm demarcation.

Exactly right, and what I would add is that this is a Poe's Law thing.

I might even offer a corollary to that law, which is that the more unclear a statement is, the more inscrutable a it's intent, the more likely the original author will insist that it was 'obvious' sarcasm.

This reasoning is nonsensical.

There is nothing to refute in it, but, just to prove it wrong: sarcasm is commonly denoted in spoken English by intonation.

And as we all know, it is impossible to imply tone in written text.
