For what is worth, here's yet another piece of code from the "doing
nothing" side:

https://github.com/bitcoin/bitcoin/pull/6382

It allows you to create a regtest-like testchain with a maximum block
size chosen at run time.
Rusty used a less generic testchain for testing 8 MB blocks:

Unfortunately I don't know of anybody that has used my patch to test
any other size (maybe there's not that much interest in testing other
sizes after all?).

I'm totally in favor of preemptively adapting the code so that when a
new blocksize is to be deployed, adapting the code is not a problem.
Developers can agree on many changes in the code without users having
to agree on a concrete block size first.
I offer my help to do that. That's what I'm trying to do in #6382 and
http://lists.linuxfoundation.org/pipermail/bitcoin-dev/2015-June/008961.html
but to my surprise that gets disregarded as "doing nothing" and as
"having a negative attitude", when not simply ignored.
