Hi Alexis, 

One of the motivation factors for SOURCE_DATE_EPOCH was to have a 
*standardised* method for build tools to use - i.e. O(1) effort - instead of 
every tool inventing their own special command line flag that then every 
distribution each has to know about - i.e. O(m * n) effort.

The most preferable route would be to persuade upstream to accept patch (2). If 
they don't do that, then it's still worth doing option (2) over (1) because 
other tools in Debian at least can rely on this standard, instead of 
hard-coding lua-ldoc-specific logic everywhere.

Hope that makes sense,
