Are there any good solutions to the problem that redeem scripts can be lost?
For instance consider the following: Alice, Bob and Carol lock funds in a multisig 1of3 P2SH output. Alice has the ability to unilaterally spend this output. However she loses that ability if she loses the redeem script. It is easy for all parties to create offline backups of their HDseeds, but Alice can't predict Bob or Carol's pubkeys so if Alice loses her redeem script they gain the ability to lock her funds indefinitely. One solution to this specific instance is to use HDSeed pubkey deviation so each party can regenerate other parties pubkeys.

A general solution is to stick the redeem script in an op return to the transaction which funds this output, but I'm not aware of any wallets that do this. Are there other general solutions to this problem?
