Immediate rematches should be for inconclusive fights

[the ambush]

Rematches have almost always happened(or not) to suit the UFC's bias towards certain fighters.

Just about the only one which comes to mind which bucked that is Shogun/Machida 2 were I think the negative reaction to the decision was so bad they could not avoid it.

Immediate rematches do not bother me as long as they happen consistently. Rampage/Forrest was close yet no second fight. Rampage knocked him down cleanly in a couple exchanges.
