In most cases it seems to me that the considerable research won't turn
anything up. That seems especially true of the kind of bios that have
turned up here. But I am thinking also of the thought that someone
writes an article one some person, giving no real evidence for
notability, and it's up to everyone else to dig that info up. My gut
reation is, you want something in the encyclopedia, it's generally up
to you to justify that when you put the article in.
