I guess that the 2024 backgrounds will result in a lot more players taking Magic Initiate (Druid) or Magic Initiate (Cleric), giving them access to this spell and Cure Wounds, among others. This is generally regarded as the better healing option in combat, though non-primary casters will probably swap this out for a utility spell at higher levels (for example, a Guide with Druid Initiate might choose Goodberry at level 4).

Interesting how healing spells went from necromancy, evocation, to abjuration.

So if i'm reading this correct now it can heal undead?

Correct. All of the healing spells in the 2024 Player's Handbook have had the old restriction against healing constructs and undead removed.

It's possible that since they removed the undead restrictions and more recent species options have expanded to allow for more unique creature types besides humanoids such as fey, ooze, and monstrosity type player characters, that we might get species options in the future that are constructs and undead. The other explanation is that they just wanted to simply a lot of spells that had needless restrictions so healing lost all the limitations for undead and constructs, hold monster doesn't have a random restriction to prevent its use on undead, etc.
