Well I wanted to create an easy and familiar process for people installing from source, so I wanted it to be roughly git pull && ./configure && make && sudo make install. So I didn't consider restoring mtimes into that flow, just looked for options for autoconf to not regen. Also I think it took quite a while to even realize the mtimes were the issue from an error messages, as I was not very knowledgeable about autoconf / automake.
