   Since #10885, bitcoind is expected to reject symlinks to wallets. This behaviour is also intended to be tested in the following test:https://github.com/bitcoin/bitcoin/blob/86528937e5c4da2e12c46085fc41e87ed759258e/test/functional/wallet_multiwallet.py#L168-L170

   However, this is not the case:

    0$ ls -l ~/.bitcoin/regtest/wallets/

   Symlink to a wallet directory is allowed, but a symlink to a wallet file is not. What you’ve tested manually is a symlink to a wallet directory, so it works.
