Safari has supported grid-gap since March 2017, the exact same time Chrome and Firefox has. Your statement is completely false.

Gap support in Safari is only there since April 2021 (last month) and because the usage is still close to zero you can't use it. https://caniuse.com/?search=gap

Gap is not grid-gap, and what was added was specifically for gap in flex containers.
