The PEQ server team (specifically Cavedude) is the lead on building the original DB, which in turn based HEAVILY on data submissions from data collectors, which has been few in the past 10 years. No data - no DB.
The items Db most likely also covers things well past GoD, but I am not sure.
The zones are there if you have right client and you can zone anywhere you like - but they will be empty - no mobs, no scripts, no loot tables.
If you looking for actual "replay EQ" experience, then P99 covers the Classical age up to Velious, PEQ and bunch of clone servers are up to GoD, and the rest are on custom content using random zones from all over. Most, if any, content past level 70 is custom made and has practically no relation to original 70+ content (see The Hidden Forest or StormHaven for example).
In short - no one really cares for original 70+ content, because, again, 99.9% of people here quit in 2004, and mostly interested in the Classical era
