I would think that a Arahat has shed those states so it does not
matter at that point.
The jhana are not going to be the same for everyone perhaps.
Similar in taste likely.

Jhana is tied also with siila and panna so i do not know if it is a
stict line.
Not all people have equal levels in all 3 regions
They are also subject to crossover.
To act in quietude and wise effort is not easy I beievve.
Why stuggle for samadhi even.
Does one only "get" Jhanas while in traditional meditation positions?
I would not think so.
Enough of my ramblings anyway hehe.
