Summary or problem description
I've looked at calls to "Contract.Create" and "Contract.Update" for preview3 testnet (up to block 278513) and counted 18 of them. Specifically, I was interested in manifest sizes and for this set we have the minimum value of 380, average manifest size of 1473, and the maximum of 3345. What worries me a little is that even for this set we're getting very close to ContractManifest.MaxLength which is just 4096 bytes and real complex contracts can easily exceed that.

Do you have any solution you want to propose?
Manifest is being paid for on contract creation/update equally to the script itself, so restricting it to such low values is just not necessary, we can make MaxLength 64K and forget about it for quite some time.
