Unfortunately this requires all ports to include an mtree file. Relying on 
port maintainers who are human to ensure that these files are created and 
updated when ports are created and maintained will result in more human 
error. I've learned over my long career to rely more on automation than 
human beings. Automation [should] never fail and when it does it does 
temporarily until the bug is found and fixed. Human beings inconsistently 

If it were an auto-discovery script that created an mtree file as part of 
the packaging process, it would be another matter. But this optional 
solution path should be discussed on ports@, not here.
