Ah, well, if you plan on importing LWO/ASE and MD5, then it’s awesome! 
I probably wouldn’t worry about MD5 too much right now, since if someone makes a map for UE4 in Radiant, (s)he won’t use MD5 and would most likely simply export animated model into FBX instead (there is only one working MD5 exporter, and at one point it will be obsolete).
