I don't know should I call it disadvantage or a cautious- If I'm correct, when you import your paper wallet private key, you have to spend all the coins at once because if you use small amount, the change may get lost. So, first you should import the key and send all the fund at once into your another wallet. After that, you can spend small amount.

In the case you want to spend a partial amount, the remaining balance will be lost only if you make a transaction with createrawtransaction and don't specify the change address. In that case, all the remaining balance will go to the miners.

If you create a wallet in electrum with a single private key and make a transaction, the change will be sent back to your paper wallet address and you won't lose the change.
