If you want to make your ERC-1155 contract upgradeable or you hit the max contract size limit then consider using the Diamond Standard, which is EIP-2535.
ERC-1155 mentions EIP-2535 in the Upgrades section.
ERC-1155 says this:
To alleviate the need to emit events when changing contract address, consider using the proxy pattern, such as described in EIP-2535. This will also have the added benefit of providing a stable contract address for users.
Also, one of the authors (Ronan Sandford) of ERC-1155 is currently building tooling for EIP-2535. Here is a link to his announcement: https://twitter.com/wighawag/status/1280992800545349644
Here's a couple articles about EIP-2535:
