Why does mojang doesn't add skins on minecraft pe?

MOJANG IF your READING THIS:

WE PAYED 6.99 FOR THAT GAME
WHY DON't you ADD A FEATURE WE CAN UPLOAD SKINS TO THE GAME?!

SRSLY I'm MAD, your GONNA MAKE A MULTIPLAYER MODE BUT NO SKIN UPDATE CAME WITH IT YET,
IN THE NEXT FREAKING UPDATE ADD SKINS OR ELSE!

WE NEED SKINS So NO ONE CAN't HAVE A HARDTIME JAILBREAKING OR ATTACHING THE DEVICE ON THE COMPUTER WHICH MAY CORRUPT FILES!

to answerers:
so why does mojang don't wanna add skin features for minecraft pe?
we need skins so we can be identifiable at multiplayer and i just wanna be pretty
and make myself cute on my portable minecraft when i'm on vacation without my pc (i'm that type of person who loves games with character customization and stuff and i just like making my own character)

MOJANG NEEDS TO ADD THIS QUICK OR ELSE I'm GONNA GO TO THEIR COMPANY? AND RIPS EACH MENS BALLS OFF

One reason Mojang might not have a skin feature on the Pocket Edition of Minecraft is that the development is still very early. They haven't spent a lot of time coding and developing the Pocket Edition and are mainly focusing on the PC edition and some time on the Console edition due to the popularity on those platforms. I wouldn't be surprised if they introduced a system to change or upload skins in future, but for now you will have to put up with the default Steve skin. Just give them time to add the feature as they are trying to apply lots of updates for lots of peoples needs and requests.

I might be completely wrong as I haven't played Minecraft in over a year and a bit, but it could be a possibility.
