It doesn't matter whether it's points or pools.
The point is that WotC already designs lineages and classes and subclasses by looking at like vs like features for balance. Spells, feats, ability score modifiers, and proficiencies are basic benchmarks that can be weighed against one another, while ribbons are essentially tax-free.
They're giving us some sort of build-a-bear lineage system, and that means that the features have weight, they're not just equally replaceable. You can hide the weights by pooling types of abilities together, but if you're saying "If you choose Darkvision, you don't get x bonus feature" then it's point buy, just with a friendly face on it.
