The name of this plugin is somewhat deceptive as there are a LOT of other changes that happened over the years.
In addition to the ones abrandnewday mentioned, the ones I know are missing are:
- In Beta, Soldiers only had 20 rockets total (4 in clip, 16 in reserve). Current game they have 24 (4 in clip, 20 in reserve).
- Teleporters and Dispensers only have one level. Dispensers were the equivalent of the current level 2 Dispenser, teleporters were the equivalent of current level 1 teleporters.
- Sapping one end of a teleporter didn't sap the other end.
- Spy's Invisibility watch didn't recharge from ammo boxes.
- Spy's knife did backstabs veeeery slowly. Like it would literally take 1 second unless you started stabbing before approaching an enemy.
- Heavy's minigun various buffs and nerfs would have to be undone.
- Pyro's Flamethrower damage buff would have to be undone.
Oh, and of course, the game only had 6 maps: cp_well, cp_dustbowl, cp_granary, cp_gravelpit, ctf_2fort, and tc_hydro. Oh, and these maps have had changes over the years as well such as the side door on the granary ramps near mid.
There are also better ways to restrict the things this plugin does cover, such as applying attributes using TF2Items... there are specific attributes to block airblast (2 actually, but only the Phlog one is in active use) and block Engineers from picking up buildings.
