Based on the experience from the last deployment. I don't think it's possible to close any account created in any of the Ix declared in the program (where, ofc, the program itself is set as the authority) if we don't explicitly declare an Ix to close it: pub fn close_<any>_account().

Yes, naturally, because programs can't initiate txs on their own. So, to act on behalf of the SolSab programs (which have authority over the accounts they can close), we'll need explicit Ixs handling this logic.

Similarly, we'll need separate Ixs for #170.
