There are a number of issues with adding arbitrary size restrictions to consensus(I personally think it's additional complexity for negative gain), but most of all this may resolveĀ in burned coins.

The recent 998 of 999 multisig segwit transaction highlights a problem with BIP144. As the solution applied for btcd shows, effectively a single transaction witness can be the same as the maximum block size.

11000 bytes may not be so unreasonable but now there is a special case with a block over 33k worth of witness data.

A concrete limit should be set on the maximum size of a transaction witness, and this should be discussed in a more general sense about total transaction sizes.

In the absence of a specification, it becomes impossible to properly implement and the status quo devolves to the actual implementation in the bitcoin core repository code.

I think the weight calculation should escalate exponentially to discourage putting transactions like this on the chain. The price was equivalent to about $5 to do this.
