BIP author: @sipa
Recently, a developer learning about Bitcoin contacted me with some questions about BIP66 and I discovered through our conversation that he wasn't aware of what I believe is this important context for the soft fork. I sent him a link, but I'd like to propose linking to it directly from the BIP for the historical record.
I know modifying final BIPs is frowned upon, so if this is unacceptable, I'll add it instead to the wiki page indicated by the Comments-URI field.
