Type O is for basic,standard Bioware only .Neither for Alpha,Beta nor Deltaware
Debatable. Augmentation, p.20 says: "Off the rack, basic bioware is considered delta grade".
'Basic' can refer to basic grade or basic ware (thus excluding cultured).
However, there is no grade that's called 'basic'. Grades are Used, Standard, Alphaware, Betaware and Deltaware, so it's reasonable to assume that every type of basic bioware implant counts as having its essence cost halved, while e.g. a synaptic accelerator would be excluded.
Furthermore, 'Off the rack' would include alpha grade.

Bioware (type O) is available ready-made in basic and alpha grades from a number of corporate suppliers and bio-banks. Betagrade and better bioware must also be tailored to and grown from the intended recipient’s tissue, just like cultured neurological bioware.
It's not quite as clear as you make it out to be, however the point stands: Beta and Delta grade bioware are excluded from the multiplier of Type 0 System.
