What prevents lemmy team from making Cardview on mobile like Hexbear?

So the question is clear from the title. i was searching the web and found a website called Hexbear https://www.hexbear.net/. after looking at it for a minute found that this website is a modified fork of lemmy, but checking further found that hexbear shows the posts in cardview which looks better than the standard view of lemmy on mobile.

Any plans to allow cardview for lemmy on mobile?

here is how it looks on mobile
