Now that Microsoft is closing Publisher...
Scribus developpers should enable the use of Microsoft Publisher files (.pub) on this software.
or create a plug-in to convert Microsoft Publisher files (.pub) into Scribus file format within Scribus it self, to gain all Publisher users in search of a software to continue to work with those files they still need.
This a suggestion that could be benefic for Scribus...
You should do it right now!
Hey Bouzzi
... Actually, Scribus does have (limited) import from Microsoft Publisher files.
In the era of AI, you're welcome to setup your agents fleet and provide Scribus with patches that improve even further the support for .pub files!
