What problem does your feature solve?

Contracts can hold value and with the rise of smart wallets being able to airdrop funds to contracts will be increasingly important.

What would you like to see?

e.g. rpc.requestAirdrop(contractId) should work vs:

{
  "type": "https://stellar.org/horizon-errors/bad_request",
  "title": "Bad Request",
  "status": 400,
  "detail": "The request you sent was invalid in some way.",
  "extras": {
    "invalid_field": "addr",
    "reason": "invalid version byte"
  }
}

What alternatives are there?

You have to fund a G-address and then use the SAC interface to move funds from the G-address to your C-address. It's a bit cumbersome.
