The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Tyoe of Shamir's Secret Sharing used in Ledger Recover?
I am very sure it won't be. Trezor and Keystone use SLIP-49 which has some shortcomings which were improved upon by SSKR.

Isn't a strong bip-39 passphrase enough?
SSKR is an improvement on SLIP-39. SSKR comes with a seedtoolcli. Tezor hardware wallets use SLIP-39 if you have one of those.

SSSSS - Non-native Shamir Backup for seed phrases
SLIP-0039 is not is not round-trip compatible with BIP-0039. SSKR / BCR-0011 is based on SLIP-0039 but improves upon it by adding this compatibility.

Splitting BIP-0039 Mnemonic
Please see the discussion here: https://www.reddit.com/r/ledgerwallet/comments/ibkls4/does_ledger_have_plans_to_implement_shamir_secret/ Maybe ask here if the Ledger developers nicely if they still plan to implement Shamir's Secret Sharing, If Ledger do not implement Shamir's Secret Sharing (e.g. SSKR) then maybe consider purchasing a Trezor which implements SLIP-39. Bear in mind that SLIP-39 is not round-trip compatible with BIP-39.

Getting MultiSig Protection with a Single Hardware Wallet - Could be a better solution.... For personal vault
Or use a single hardware wallet that implements a version of Shamir Secret Sharing (SSS) e.g. SSKR and store your steel share backups in multiple locations.

Ledger devices CAN send your seed phrase over the internet, confirmed by Ledger co-founder
The link didn't seem great, Seedsigner uses a Pi Zero, I have no experience with it but it looks interesting especially for the for the somewhat paranoid.

Came to crypto because of altcoins, here to stay because of Bitcoin.
Coldcard is a solid, bitcoin only commercial option. If you don't mind a little DIY then Krux or seedsigner might be a good choice too. You can also make your own with an old laptop. Remove the WiFi functionality (rip out the board or antenna) and upload Linux. Install a wallet on there like electrum or sparrow (transfer it over via usb) and you have an airgapped wallet.

Anyone have insight comparing SeedSigner vs Jade?
For Seedsigner it's capable of deriving P2SH and P2WPKH adresses. But there's a github issue open, that could bring your requested feature. Let's see...
