Yes. Once you have backed up your parent seed and passphrase, any following child seed you generate doesn't need to be backed up. All you need to backup is the index number of the child and whether it's a 12 or 24 word phrase.

If you ever need to access a child you can simply use your parent seed backup and entering the correct index number will give you your child mnemonic.

It's far better than having dozens of mnemonic seed backups

Plus, if any child's are compromised it doesn't affect the parent in any way.

I see, so you only need to backup the metadata (index, seed length) for each child metadata.

I wonder if it's cryptographically possible for wallets to search index 0-100 and list them automatically, eliminating this requirement.

That would be extremely powerful, covering 99% of usecases with zero backups of child data.

It's useful because your parent seed can be safely stored offline in steel and then any child seed index numbers and passphrases can be saved in your self hosted bitwarden instance without worrying up where and how to backup the mnemonic seed.
