Is this really such a good idea right now?

If everybody starts using spv, from where can you download the blocks, if nobody stores the blocks anymore?
I guess we should wait, until real block chain pruning is implemented, otherwise the amount of full nodes will go down,
which is no good right now. You could end up harming the network more than helping.

A good question. This is actively being discussed right now on bitcoin-development.

See for example Peter Todd's post about an alternative approach with partial UTXO sets:
