Why some "obvious" and requested features are in DbD mobile and still not on every platform ?

I mean DbD mobile, besides it's poor aesthetics, has a ton of accessibility requested so many times by the community but our devs seems kinda deaf about it.

.Perks notifications below your characters, (premonition, spine chill)

.Your heart appearing when the killer is in your terror radius.

.Chase effects. (like legion feral frenzy)

And so on. Make the game more understandable and even more inclusive for the deaf people who's around. or even people who has bad speakers or audio features.

So why any of those suggestions made into DbD mobile but is still not planned on every other platform ?
