I personally believe that while I often just set the name explicitly when saving, the idea is great. I have a different and IMHO bigger problem, though: when I right-click on the download link in FF and select "save target as", it wants to save it as [download].htm which is much more annoying than than 123456.pl - I have to open in a new tab and "save as"... I don't know whether that's an issue with my browser/system and if it's fixable on the PM part.
