Did you even think about this yet?
1) Third party patches aren't gonna be supported by Blizzard, especially since they're made WITHOUT permission
2) People rarely look at the patch site unless they need a manual patch
3) How would someone revert the changes? Creating multiple .exes would clutter the entire folder and be confusing
4) Mods will screw up basically every single ums/melee game since the maps weren't designed to be used with them
5) People playing without the mods will drop which will piss other people off
6) I highly doubt Blizzard would be willing to host the mods on their servers
