🗒️ Summary of this message: Aggregating proofs may be manageable, but if miners do it, full nodes must still perform non-aggregated validation, increasing costs for all. Consider a separate network for aggregation.

Are miners supposed to do this aggregation?
If miners do this aggregation, then that implies that all fullnodes must also perform the **non**-aggregated validation as transactions flow from transaction creators to miners, and that is the cost (viz. the **non**-aggregated cost) that must be reflected in the weight.
We should note that fullnodes are really miners with 0 hashpower, and any cost you impose on miners is a cost you impose on all fullnodes.
If you want to aggregate, you might want to do that in a separate network that does ***not*** involve Bitcoin fullnodes, and possibly allow for some kind of extraction of fees to do aggregation, then have already-aggregated transactions in the Bitcoin mempool, so that fullnodes only need validate already-aggregated transactions.
Remember, validation is run when a transaction enters the mempool, and is **not** re-run when an in-mempool transaction is seen in a block (`blocksonly` of course does not follow this as it has no mempool, but most fullnodes are not `blocksonly`).
If you intend to aggregate transactions in the mempool, then at the worst case a fullnode will be validating every non-aggregated transaction, and that is what we want to limit by increasing the weight of heavy-validation transactions.
