It's not just getting those features implemented, but also shipping those to the user. Safari is the only browser that doesn't have autoupdate and has versions tied an operating system in 2023 and that's one of the biggest problems.
While you can be happy only supporting say the last version of all other browsers, Safari requires you to give it years before the marketshare of the new versions are enough that you can migrate to new features, thus making the fact that webkit had implemented those features first completely irrelevant.
Furthermore, the fact it only runs macOS makes it a true pain in the ass to test, you need to have access to an apple machine to test it, be it virtualized or remote, which sucks because even Edge has support for Linux at this point.
Even worse is the fact that there are indeed a lot of features Apple simply refuses to implement, specially related to PWAs, which has slowed down the adoption of PWAs by at least 20 years, ane that's if they ever make a comeback after the crippling Apple did to them to maintain App Store supremacy.
I could go on and on and on and on. Webkit is great sometimes, but Safari absolutely sucks and has been slowing down web development ever since IE stopped being a problem for most developers.
