workflow().name provides the Flow guid but there is nothing in the workflow() context that has the Flow Name at runtime. I might suggest something like workflow().displayname.
An example of how it could be useful might be a Flow designed to send an Email having the Flow Name as the subject of the Email.
This feature was recently completed, you can read more here: https://flow.microsoft.com/blog/return-data-to-powerapps/
Nintex offers this option, which is a HUGE time saver to troubleshoot a problem like when a workflow email is forwarded to the helpdesk but then they don't know where it's coming from. Have the full display name of the workflow, the author or a link to the flow, it's a massive time saver.
I would ask to add the flow version as an attribute in case the flow has been upgraded or updated....
This solves the issue I was havingworkflow()['tags']['flowDisplayName']
