If by 'soft' you mean 'generally more invested in the mental and emotional journey of their characters and more inclined towards immersed character play' than the highly disposable burner character style of play that was encouraged by older editions, then sure, call it that. It's a roleplaying game, and the more recent renaissance of D&D has focused more heavily on that - roleplaying - than on having to reroll a new character every few sessions and not really getting attached to any of them because you know you're going to have to reroll again in a few sessions time. To each their own; plenty of groups still play like that, and AL games are generally very min-maxed as well... but it's not the main pitch any more.
