Indeed, as was mentioned by Mark there is a read-only support under Topology Management node in frame navigation

As well there is a possibility to create a mapping under "Publishing" tab of publication properties 

Something to consider for new Experience space under Administration feature 

Let's collect some votes to see how important this UI interaction with Topology Manager is

GUI for managing Topology Manager

Since it's introduction in SDL Web 8 in 2015, Topology Manager items are managed using PowerShell scripts. It would be good to to have a GUI accommodating reading, updating and removing Topology Manager items.
