Hades 2 developer Supergiant Games understands it's hard to move on. You were always going to miss some of the roguelike's Early Access features, though you should try not to dwell on it. Creative director Greg Kasavin assures players that some of those "missing" Boons are still present in the game's final version – they're just different.
"In the particular case of Smithy Sprint," Kasavin tells GamesRadar+ about the powerful Boon that triggered blasts when dashing, "we wanted something simpler and easier to use for one of the main Boons from the god of the forge, though as part of that we moved the general concept of keep-sprinting-for-a-big-blast to be integral to the Black Coat weapon's Aspect of Nyx. So, please check that one out if you haven't! I really like using it personally. Sometimes ideas for Boons and abilities find new homes in this way!"
