Nostalrius Begins - Quality wow vanilla realm (1.12)

Will it remain 100% vanilla for is this server gonna evolve with more and more expansion while remaining with the vanilla vision?

I first tried wow when TBC was already out and i totally hated the idea of flying mounts in my mmorpg. Then WOTLK came out and i disliked the idea of quest tracker so i left during the trial of that game. I know i can disable it, but i hate the idea of the whole server having it the easy way while i stay behind players i started off with just because i decided to play without the extra easy mode feature.

Also, i never seen what vanilla was, but when i see the description of this private server and what it is trying to maintain like not introducing flying mounts, i have to ask, is this game gonna eventually evolve with the expansion while maintaining the whole feeling of old vanilla ways?

If I am rigth, this server will remain at 1.12 version until death.

In the FAQ, it is stated that one day (in several years?), a TBC server would be opened and people would be allowed to transfer for the launch (as if their server was just upgraded to TBC).

This is however a very long term project, so take it as uncertain, in my opinion.
