Question on Phinigel 'classicness' and p99 response

[Rygar]

Did a search here and didn't find anything... I'm curious, with the new EQ Phinigel progression server, is the content truly being considered 'classic' to the p99 staff and community? I know there is raid instancing (blah) and content unlocking every 12 weeks, but that aside, will that content that gets released be accurate compared to classic EQ timeline (i.e. no new mobs / loot tables added that came many expansions later)?

What I'm getting at, is if 'new content' is discovered in Phinigel (old EQ has said there were a multitude of undiscovered quests), would p99 update accordingly or not accept this as being classic because 'you never know' if it was added in / fixed?

Furthermore, for zones like the Hole I remember there being slightly different loot tables and a named steel Golem I discovered during Velious era in Golem Tower but was never documented on EQ bestiary or Allakazam's.

Any dev feedback is appreciated, I'm debating making a 'discovery' toon that I wouldn't level much but just gather some intel on mob spawn points, etc and compare to p99. Just wouldn't want to waste my time if Phinigel isn't being considered 'classic content'.
