This seems to be an abandoned upstream project 
(https://github.com/ramonhagenaars/typish shows the last commit in 
August 2021), which given the pace of development of Python type 
annotations seems a rather risky thing to rely on.  As far as I can see 
nothing else in Debian depends on it.

Roland, you packaged this relatively recently, but 
https://bugs.debian.org/1108191 doesn't say what you needed it for - do 
you actually still need it in Debian?  If so then pragmatically it 
probably needs somewhat more active upstream maintenance ...

Thanks,
