The mechanics are all incredibly easy to understand after seeing them once or twice, especially with the bajillion guides out there. This doesn't need to happen, Echo is broken enough and I hate how First Coil was ruined with it.
First Coil would've been 'ruined' just from the fact that people can now easily get 30 item levels over what it was designed for.

Either way, seriously, the existance of a Coil Lite doesn't somehow detract from your accomplishments or damage the original fights. Hell, if Coil Lite existed, there wouldn't need to be an Echo implemented in previous sections of the coil. Those who still want the challenge can get it, those who don't, don't have to.

Seriously, if you're going to argue it should only exist for those who really want to step up to a challenge, why do we still have normal Second Coil when Savage exists?
