a user of mine had an idea for a bio component

We already have one by Michael, but he had another idea:

When you open the profile of a user, there should be a container above the wall container with the label "tell us something about yourself" with a pencil icon for direct editing - here the user has the possibility to add a few words about himself so other users who visit his profile, can directly see a few infos about the user he gives about himself.

something like "hi my name is Dominik, I am 27 and I like to play games and go hiking"

Something like the bio component, but with fewer words and directly visible when opening a profile

makes the whole thing a little bit more personal, especially for mobile users

Would this be hard to implement?
