I think the only custom policy that this change would make harder to = implement is the current default policy of 5% reserved space. Right now, = in e.g. CreateNewBlock, you have two loops, each of which follows a = completely different policy, plus additional code for corner cases like = ensuring that a tx isn't added twice. If I were a miner and a mediocre = programmer (which I actually am, on both accounts), and I wanted to = change the mining policy, I would probably take a look at that code, = groan, give up, and go sharpen my pickaxe instead. This change could be written in an abstract way. We could define an API = that is calibrated on the whole mempool, then has a method that takes = transactions and returns priority scores. If someone wanted to write a reserved-space algorithm in this priority = API scheme, then they could just set it up so that most transactions = would get a priority score between e.g. zero and 8999, and any = transactions that were supposed to be prioritized would get a priority = level over 9000.
