Enjoy debugging some application that opens that many files at once!
I suspect the risks are organizational more than technical except
for programs using expect() system calls. More resources for a
rootkit to use if you get cracked, more interaction of two programs
opening the same file without checking optional locks, etc.
Many of the original limits come from a time when memory was much
more expensive.
