Substantial QA requirements/testing time & complexity. The update to 
1.8.x issue is here:

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=230140

It will need to be updated to account for 2.1.x series, perhaps even 
considering multiple port versions if there are further backward 
incompatibilities
