There is a reason as to why it is missing. Ticketer who have try to portray themselves as the really helpful company with BODS and they deal with it all for you, it costs £100 per month, per ticket machine (That is in addition to the licence fee and other addons which they offer) for them to do the AVL feeds. That is a lot of money for companies, more so given that many independents are already struggling. It's just not viable for quite a few of them.
I think it's worth saying that while the legal requirement is in place for the stuff to be done, the DFT has extended the date unofficially (else it would have to go through parliament to amend the dates). They will not be enforcing BODS until the end of this year and KMPG have been instructed to continue supporting operators through this extended transition period.
First Manchester isn't on the system yet (Maybe an oversight)

As for your second point, Firstly, S19/S22 operators tend not to have ticket machines. No ticket machine or certainly no ticket machine capable of tracking. If they do have a ticket machine though, I refer you to my first paragraph which shows it is very cost prohibitive. It would disproportionally affect these operators too much. You can also look at their main users and you can see that they aren't the people who would be going online to track the bus.
