I don't wish to be overly critical, but to get satisfactory answers you might want to ask more specific questions, unless you're only asking for opinions or craftily stating your own.
For example, I don't know what 'fully implemented' means, and the answer is almost certainly no for all three factions.
Alliance doesn't have military ranks at the moment, maybe it never will, or faction-specific ships, as the other two major factions have.
But this could be explained in lore by their looser military and government structures. It may be that certain ships will only be available to 'Friendly' or 'Allied' players, for instance. Or not.
But the capital Alioth, and the systems around it, have been buzzing with Cmdrs recently, and there have been attempts to expand influence in the area using the background simulation. It doesn't seem any less 'implemented' in that respect than the other major factions, or independent systems.
It is true that the Alliance does not yet feature in the injected storylines, but that doesn't mean you can't take part as an Alliance loyalist.

Let the bootlickers, and those who confuse capital with human values, weaken each other and fight themselves.

If my Alliance rep is artificially borked by FD I will be a) very surprised and b) furious. Won't ever happen is my guess.
