That is not the problem, in fact the problem is the absolute opposite.
When a new port is generated not enough of the changes are factored
back into the MI code - leaving far too much code MD.

Factoring anything back to be MI is actually a problem due to the
number of ports that have inconsequental changes to certain functions,
and some differences between the ports (eg major numbers and the location
of the disklabel on an MBR disk) that really shouldn'y have been allowed
to happen.
