Arguably, a transitory spam attack, yes, but with a speculative rally brewing (and implied increases in network usage) this BIP may prove to be just-in-time. Solutions favoring dynamic vs. scheduled increases in blocksize (and by how much) are interesting and the proponents should explore and map out their proposal with data sets, trend projections and future scenarios. It will require labor and time, but convince the list about the scientific merit of your proposal. In the meantime, the current "sufficient" state of network capacity may soon experience "insufficient" moments. Developer confluence around a workable plan and testing should, reasonably, begin now. Jeff's proposal addresses an approaching capacity crunch whilst honoring decentralization and providing time for testing and alternative future innovations. It's the best solution the user base and developers currently have for all the reasons Jeff gives: conservative blocksize increase, added capacity, low impact and minimal implication for the network and its users. Then, many of the more far-reaching proposals being offered can be tested, formalized, and fleshed out with scenario data.
