Relic weapon enhancement redesign mentioned in PLL

Looking for anyone who can point me to some kind of elaboration if there's been any.

> Incidentally, the Development team has been talking about redesigning the weapon enhancement process, so future series might shift from the current style of quests.

This is hard for me to interpret, given that we've had:
Tomes
Instance / Open field (Atma)
Light farm

as part of the relic steps, and I can't understand if they mean to do away with one of or the entire of these options.

I really would like more emphasis in the field instance like with eureka/bozja, and I am feeling disheartened if we move forward with tomestone only, for example.

Any discussion is welcome, as well as your own thoughts, but I do just want some kind of elaboration.
