| StyleX had already been in development for a while, organically inspired by React Native's StyleSheet API—which itself was influenced by inline styles. |
| React Native pioneered the approach of merging purely by key, and assigning | ||
| different priorities to different properties. Longhand properties have a higher | ||
| priority than shorthand properties. So, while you *can* end up | ||
| with a style object that has both `padding` and `paddingTop`, `paddingTop` will | ||
| take precedence regardless of the order in which they are applied. |

Meta engineering write ups typically focus on describing specific problems/opportunities we encounter, the root cause, how it was resolved, and the results seen. In that context, I think the voice and framing used throughout this draft could be revisited.
Another concern I have with this post is that one of the primary goals of StyleX was to optimize the output. One of the defaults doesn't do that, but discussing it in the post isn't particularly relevant to the main topic of the post.

This is very useful feedback! It helps me use a particular framing to do a second draft.

It does have limitations so this may be misleading
