With 5/5 Divine Fury and a BT buff, without accounting for Haste, GH is a 2s cast. So in cases where you have Penance on CD or are saving it (say for Fusion Punch, Plasma Blast, etc.), you still have a higher HPS option than FH. Hell, even without the BT buff, GH is higher HPS than FH, the only real drawback is that it's more mana intensive, but there are situations where pure HPS is more important than efficiency, and that's a tool that Divine Fury provides that you wouldn't have without it. Compare that to Imp
As for your examples, none of those are situations that Improved Renew is even useful. For Malygos, you should be spamming PWS during the Vortex and letting the Holy Priests and Druids handle healing. For Loatheb, Renew is pretty worthless since no heals work for 85% of the fight, but absoprtion mechanics do, so you should be spamming PWS and hitting pre-casted Greater Heals or Prayer of Healings followed by a Penance in the healing phase. And why are you even healing Life Tapping Locks at all? Again, let the Holy Priests, Druids, and random AOE handle it; if you have to heal them, unimproved Renew is more than enough as it is, and a Flash Heal works just fine too.
And to bring it back on topic, Renew just isn't useful in Heroics as Discipline. You get better throughput and efficiency out of the same GCD on the MT with a FH than with a Renew, and your DPS can get a PWS if you are expecting damage (much like when Holy would use Renew), or you can just FH to get them topped up right away.
