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.

- Can ledger create something like Shamir backup, where users can manage the shards by themselves?

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.

It has already been done by a third party developer https://github.com/aido/app-sskr-check - you'll also have the option to use Recover with your own setup if you wish
-
Ledger Recover as an app?
I have been working on a Ledger app called app-sskr-check for generating Shamir's Secret Shares, similar to what Ledger's new Recover service does. App is available on github for people to review.
