Here’s another reason for this behavior to be aligned with the rest of the browsers.

There’s a popular technique of CSS lazy loading introduced in Filament Group blog in 2019 https://www.filamentgroup.com/lab/load-css-simpler/

<link rel="stylesheet" href="/path/to/my.css" media="print" onload="this.media='all'">

I see it used and mentioned here and there as one of the best and simplest option. The article states:

> …the browser will load the stylesheet without delaying page rendering, asynchronously

Which is not the case for Safari: it will be Render-blocking. No one seems to expect such incompatible behavior.
