Hi,
I noticed that, in the current implementations of XEP-0444 are not really backwards-compatible. Non-compliant clients completely miss the emoji reactions and the users are completely unaware that the reaction has been sent.
Even if it not mentioned in XEP-0444, XEP-0428 can be used…
One idea would be to provide the following as a fallback:
Content of the original message đŸ˜€ …and that's actually what Cheogram Android does. You can see an example of such reaction+fallback stanza in this test case: <https://git.sr.ht/~nicoco/slidge/tree/master/item/tests/test_shakespeare.py#L558> Is there any reason why there is currently no fallback mechanism in XEP-0444?
It gets rapidly messy in groups. One of the values of emoji reactions is to improve signal to noise in large groups, and non-supporting clients will have a ton of noise with fallbacks. There are also other not-so-edge cases that are annoying to handle: reaction to attachments, modification of reactions. That said, I think in 1:1 chat it would be quite reasonable to include a fallback, as the signal to noise ratio is not an issue there. Again, XEP-0444 does not forbid it, it's a up to client (and gateways ;)) developers. -- nicoco
