Primal including other reactions would also make nostr's network effect less biased in favor of centralization-minded people.
Right now, Primal's trending feeds are basically nostr's biggest content discovery system, and the trending system is biased to favor the opinions of people who use Primal instead of apps that support emoji reactions, since Primal doesn't count those reactions.
This meme I posted a little while ago is a good example. It currently has no engagement according to Primal, but nostrudel shows 2 reactions from 2 different npubs, which would generally be enough to get into the 1h Trending feed these days, possibly attracting more engagement. It's a subtle bias with a strong effect.
Important caveat: it's possible that if these reactions were counted, then 2 wouldn't be enough to get into Primal's trending feed anymore. But it often only takes 1 reaction, so it couldn't be too far off.
My DVMs still count them. They are available in primal. At least those who are not personalized.
