Drop-downs for unconstrained lists are just flat wrong, they become unusable at a mere few hundred entries. Even with just a few thousand, you'll see only a tiny subset of accounts/groups/objects and it'll look like this:
AADEN
AADIT
AADVIK
AAIDEN
AARAV
AARIZ
AARON
AARUSH
AARYAN
AAYAN
AAYDEN
ABDEL
ABDIEL
ABDUL
ABDULLAH
...
The rest of the list will be cut off past the bottom of the screen, or have a tiny down-arrow that will scroll down... one... item... at... a... time.
I would do the "look at the server RAM disappear like a magic trick! ...and now the whole server is gone!" demo to really drive the point home, but that happens around the 200K-1M object level (depending on the software).
About 50% of the time there would be a senior developer there who would just slowly blink at me and suggest the "solution" of cutting down the directory to a more manageable size, like 50 users.
Like... yeah buddy. We'll just delete 99.975% of the user accounts in the directory system because you learned programming from a "4 Dummies" book.
