I think it's because Homunculi can't be mass produced the same way Corrupted can in certain circumstances. Homunculi requires a handler or Albedo Agent behind their creation and a lot of resources at hand, it shouldn't be something as simple as going to the doctor for PP-Up surgery. Unlike a Shaitan, which is 'just walk into funny uncharted place and be back warped beyond belief'.

Most of the LE options are arguably considered 'suicide options' in a sense, and Chimera doesn't really seem like suicide to me, more like assisted suicide. It might be to promote RP over the current mechanics. But this also brings up a concern of mine. Why GMs can't monitor/change races for special situations such as these and Dullahan.

Because lemme be honest. Imagine the amount of cringe people going "WAAA ALBIDEO KIDNEPID MI AND TURNED ME INTO A KIMERA.... I MUST KILL ALBIDEO FOR MY REVENGE PLOTLYNE..."
