It's also worth mentioning that it's sometimes critical for open source projects to be able to identify all authors of a particular part of the code. There were several cases in the past when a project had to go through a painful process of tracking down all the contributors in order to ask for their permission to relicense the code. Without version control history this would have been much harder, if not impossible.
Besides that it just doesn't sound right to throw away potentially valuable historical information just to avoid a manageable amount of work. After all the conversion has to be done only once. No to mention that if you don't migrate the history, there is a significant probability that you'd regret not doing that when it's already too late.
There is also a precedent to the contrary. When Linux migrated to brand new Git all the historical information was discarded. Probably the reason was that the metadata was stored in a proprietary Bitkeeper repository and obviously there were no migration tools available at that time.
