Some controllers which were made for such as SASI to MFM, and QIC and 
the like had place holder jumpers on all the pinned connections because 
they were not being packaged by the vendors, and having customers 
package them in odd places left the chance that they could have things 
drop on those connections.

Also on boards which are conformal coated they are common as well when 
used.   Usually with some other means to secure the option area.
