Won't spammers abuse large OP_RETURNs to bloat the blockchain and make IBD take longer?
OP_RETURN data appears in output scripts. Output scripts are not subject to segwit’s witness discount. Per the block weight limit of segwit, we can have up to 4 MB of witness data, but only up to 1 MB of any other data in blocks. Output scripts are part of the other data.
Adding more output script data to blocks would result in smaller blocks. As OP_RETURN outputs require little computation to validate, OP_RETURN data would not slow down IBD.
