Spell's Tradition Trait?

[ForestDew]

So spells have their tradtions as trait(or the spellcaster's if they get it from their domain/bloodline). I haven't found how it matters. I was hoping how that someone could tell me.
(My only idea, for the future, is planar's wild magic trait that could selectively impede or annul traditions)

It's easy to see where the spell belongs with this trait.

If you are a wizard and you find a scroll with a spell which has only the Divine trait, you know you can't use that scroll without searching through your spell list.

Also the Identify Magic activity cares.

CRB page 238, Identify Magic wrote:

Using the skill related to the appropriate tradition, as explained in Magical Traditions and Skills on page 238, you can attempt to identify a magical item, location, or ongoing effect. In many cases, you can use a skill to attempt to Identify Magic of a tradition other than your own at a higher DC. The GM determines whether you can do this and what the DC is.
