I can add nothing to the best practises:

Did some testing with f5d2014e96240aab9540aaba0a792710aa7725e7.

Using `contrib/devtools/utxo_snapshot.sh` on signet I get the same `txoutset_hash`. The resulting is also identical to what I generated in earlier, see https://github.com/bitcoin/bitcoin/pull/26045#issuecomment-1739652329. I was then able to load the loadshot and sync the chain (to the tip in about a minute, wonderful) and complete the background sync.

I tested it with HWI and Ledger Nano S Plus.

--------

- I created a wallet:
`./src/bitcoin-cli -named createwallet wallet_name=ledger3 disable_private_keys=true descriptors=true external_signer=true`

- Got a new address:
```sh
$ ./src/bitcoin-cli -rpcwallet=ledger3 getnewaddress
bc1qfshzjl770c6qz560cade6ynswj2a3scqzm4a4m

- Ran `walletdisplayaddress`:

For the code here, there shouldn't be anything new to learn. It it just a different syntax, for something that can be written with `enable_if` as well. See https://www.foonathan.net/2016/09/cpp14-concepts/#conclusion

> Emulation of the `requires` clause is possible using almost the same syntax with `std::enable_if`.

> The new keys would need to be stored in a new database field

This is not actually true. Thinking about this more, I wonder if a more natural way of representing standalone keys in the wallet is just to treat them as a new [descriptor type](https://github.com/bitcoin/bitcoin/blob/master/doc/descriptors.md#reference), like `void(KEY)`, where the void descriptor would hold the key, but instead of [expanding](https://g

@achow101 any thoughts on having HWI catch this cryptic `0x6982` status code and throw a more clear error (that we can then just pass on to the user)?

@ryanofsky interesting idea, I especially like the backup implication, because descriptors can be used for paper backups.

This is the only change I did not implement. I think we should discuss further where to place this constants before moving them to the header. It seems that with every new unit test, we will be forced to move some/most constants from `net_processing.cpp` to the header.

Not sure, but this status code is specific from Ledger?

Adding one more bit to complicate and maybe explain why I described the boundary as a firewall... We build `libbitcoinconsensus.so` with guix using `-static-libstdc++` (side-note, we should perhaps move this into the build-system rather than guix).

So the idea here is that the entire c++ implementation should be compiled into the shared lib with no unresolved c++ stdlib symbols, and exporting only C symbols. That way the end-user can use any c++ impl (if any) they want without fear of collisi
