Describe the issue

I added a second new wallet2.dat. Now I wanted to encrypt it, but bitcoin-cli help does not show the command to do so, I need to use bitcoin-cli -rpcwallet=wallet2.dat help. This is very un-intuitive, and bad for a help function.

Can you reliably reproduce the issue?

1. have an encrypted default wallet
2. add new multi wallet wallet2.dat via config file or cmd line options
3. naive bitcoin-cli help does not show command to encrypt second wallet.

Expected behaviour

All wallet encryption, lock and unlock commands should be shown unconditionally in bitcoin-cli help.

The dynamic hiding of some lines is arguably worse than the benefit with multiple wallets.

Actual behaviour

bitcoin-cli help shows only wallet encryption commands appropriate for the default wallet.
