I hesitate to respond to anything you write, as you seem to have the power
to arbitrarily ban threads on this list, however...

"Suspend to RAM" is not, and never has been, the same as "Sleep"

Sleep is ACPI state S1.
Suspend is ACPI state S3.
Hibernate is ACPI state S4.

For the life of me, I can't remember what S2 was supposed to be, but iirc
not many, if any, computers implement it.

S1 is a low-power state where disks are spun down and network interfaces
suspended, but the system is still essentially on.
S3 is a state where everything that can be is turned off, and the cpu is
halted, only memory is still powered.
S4 is similar to S3 but memory is backed to disk and _everything_ powered

So no, it's _not_ logical for "Suspend" to be called "Sleep", and if your
system only shows sleep and hibernate it either means: there's a bug or
your system _doesn't_ support S3 (not uncommon).
