Yes my point was all about bandwidth and compact block relay to be more specific. I agree with you that filters, if widely adopted, make certain kinds of transactions harder to relay, meaning that parties relying on those transactions being mined according to their temporal preferences cannot build protocols that take advantage of them being mined. This unfortunately means that these parties will find other ways to accomplish their goal of getting their transactions mined in time, i.e. instead of using OP_RETURN they will embed data in the witness section of the transaction.
