This rule would cause the server to have a niche, when compared to other servers 'n systems, that isn't too ridiculous. If someone wants to be a caster, they must be born a caster, more or less.
I do not think that the Guild Thief/Neverwinter Nine PRCs were yet unlocked back then. It required the membership feats that few to no DMs knew how to grant. Thus in order to acquire the 2d6 sneak attack dice for Arcane Trickster PRC you would have had to create a Wizard/Assassin/Arcane Trickster - which limited your alignment to any evil. Back then there were perhaps too many Rogue/Wizard/Arcane Trickster/Eldritch Knights of all alignments for such a change to be very popular. Generally a great annoyance all things considered.

It would have been impossible to enforce without DMs manually checking every single character and updating some excel sheet with the level up history to ensure that no one cheated. Also, can you image something like that on a Sorcerer that gains 3rd level spells at level 6? Sorcerers would have had to wait after level 10 for their first PRC level, while wizards could take their first level after level 5. It really was not that popular of an idea.

In a way it does sound interesting, but it was just not feasible option back then. What would happen with already existing characters, and who would have scripted and coded all that? Not to mention that it didn't really sit well with the 'do whatever you want' nature of the 3rd edition D&D rules. There was that role-play argument that characters should be able to change based on role-play, instead of being predetermined and locked down by a feat taken at level one.

It was pointed out how even with Able Learner feat it made mechanical sense to take more than just one level of a skill based class. Classes come with additional perks, and some classes just have so few skill points to spare even with intelligence investment. There were also few examples how clever leveling order removed the need to take Able Learner feat altogether. Able Learner just made leveling more pleasant without need to plan your skill point investment in advance.
So yeah... the '3 by 20' was indeed the lesser of all suggested evils.

Yeah, the above was also suggested. It had some support among the evil elven Ranger/Assassin players, until the bandwagon went along and pointed out how everyone would be forced to take the 10th level of their one PRC... And somehow the evil elven Ranger/Assassins were suddenly against it.
There were also suggestions on how the first PRC taken would be free, and other PRCs or base classes would require DM permission.
So yeah, the '3by20' has its flaws, but the server really dodged a bullet there.
