I'm curious about the wallet "address space".
We all know that with a 12, 18, or 24 word seed one can generate a Bitcoin wallet in an "address space" that is so large that it would be, essentially, impossible to guess. Right?
A few questions:
Does a 24 word seed phrase fully cover the entire "address space" such that if all combinations of seed words are used, all possible wallet addresses will be mapped / addressed?
What about passphrases? Does the use of a passphrase open up new "address space" or does it map to an address in the original address space, such at seed phrase X without a passphrase may map to (be equivalent to) seed phrase Y with passphrase Z? Or seed phrase M with passphrase N maps to seed phrase O with passphrase P?
And what about the following BIPs which talk about various forms of creating sub-accounts/sub-wallets based on a primary wallet seed? Do these result in "overlap" with the original 24 word "address space"?

Thanks.
