I'm no expert but I read from time to time as well. If you want to post a link, maybe I'll learn something!
My position would be that plants evolved under conditions that created a circadian rhythm.
Plants require an endogenous regulatory network and mechanism to cope with diurnal environmental changes and compensate for their sessile nature. Plants use ...

Important things happen at night. And day for that matter. Plants, being sessile, are completely at the mercy of their environment. There are things you can do in the environment that will "hack" into a normal plant process and make a change, some of which are positive viewed by the grower. An example would be adding CO2. I don't think switching to 2/2 or 4/4 or 6/6 will bring positive results. It will be the plant being confused and not knowing what to do.
We can, for example, hack into the plant's sleep patterns, effectively putting them to sleep faster using Far Red. How?
There is a hormone in cannabis called florigen that essentially manages flower. Light flips it to a different chemical during the day in the leaves, then lack of light the plant flips it back. Ying yang all day all night. It takes a fair amount of time for the plant to fully flip that back to the Pr or dark mode chemical once lights go out. Hours. You need this to flower - its the plant signal to make buds.
Without ample dark period, I would expect a confused plant not dissimilar to a reveg.
But I've been wrong more times than I can count, so who knows.
