Why do some projects that accept TON coins require memo?

Some projects like exchanges ask users to include memo (a comment) in the TON coin transaction. What is the purpose, isn't the address enough for identification?

Sometimes, exchanges create a single wallet account, and use it to receive transfers of all their users. They need a way to distinguish between different users, and know who sent what fund to credit the correct account on their database. Memo is used here, and they assign a separate number to each user and ask them to use it when they transfer funds. Then they use this number to find the owner.

The other approach is to create a separate wallet for each user. This way, there is no need for a memo and privacy is improved, but it's harder to implement.
