There was a document from the start, but after I got the BIP number, I
was renaming the file, moving from org-mode to mediawiki and getting
the code ready.
I'm sorry, I broke the old link to the document, here's the new one:
Maybe I should create a PR already to have a permanent link, I don't know.
As said in the document, the code is now here:
Also, I should mention that one particular discussion related to this
BIP (whether we should use Block.nTime, median time or block.nHeight
for the activation thresholds) is being discussed in:
The BIP is currently assuming that the preferred choice for all
non-emergency uncontroversial hardforks is defining a starting
block.nHeight after which miners start confirming their upgrade. Once
the 95% threshold is reached the hardfork takes effect.
Long after that, after that first block enforcing the new rules is
deeply buried, that check can simply replaced by re-defining the
threshold height not with the height when miners started voting, but
simply with the height in which the rules started being enforced for
the first time (see https://github.com/bitcoin/bitcoin/pull/5966/files
