by GRE or IPSec. With this in mind, would we be safe to flag/drop/what
ever all fragments smaller than 1200 bytes that are not last fragments
(i.e., more fragments is still set)? 

No. Check previous thread about IPSec and MTU. Some IPSec implementations split the greater-than-mtu sized packet in 
half in order to avoid the possibility of further fragmentation down the road, thus better performance.
