This is the support section for the Twenty Twenty theme, not WordPress itself.
With that said, the process for filing a feature request for WordPress is similar to filing a bug report: https://make.wordpress.org/core/handbook/testing/reporting-bugs/
When you file your trac ticket, set the ticket type to Enhancement instead of Bug.
Thank you @macmanx
I have created an enhancement ticket:
https://core.trac.wordpress.org/ticket/49989
I mark this as solved, as it is not a theme issue. Sorry for this.
Many thanks!
