As Groepaz points out, the C64 KERNAL has the same piece of code. Many 
replacement ROMs (i.e. SpeedDOS and the like) already has it removed, so 
it should be 100% safe to remove it.

It is indeed one of the major reasons to why many programs do not 
survive a reset properly.

Its history would surely make a good piece of trivia. It was hardly put 
in there by mistake and it couldn't be one of those "am I running from 
ROM?" protection mechanisms as such a mechanism would surely write 
something different than what's already there.
