I watch a YouTuber named Lashmak and he added the mod and it works well with the pack and with new features in the works I’m sure it would fit well in the All of Fabric style play thanks for considering it’s been updated for 1.19.3 when ever that big update occurs in the mean time a stable 1.19.2 works fine

the most recent update added spice of fabric, which allows gaining hearts through eating unique foods, which provides a similar function through another mechanism. IMO hearty trinkets would be overshadowed by just eating more random food

If the mod added hearts in more abundance, then it would overshadow the spice of fabric mod, discounting the purpose of gathering all the foods
