That seems harmless ...

.... But those two, unfortunately, seem more likely to be abused than 
usefully used. Annoying authors would repeatedly clear any selection in 
a misguided attempt to prevent people from copying text, more often 
than application authors would use those functions for legitimate 
purposes. (Yes, you could work around this by turning off JavaScript, 
but that would work only for the small proportion of users who 
understand what's causing the problem.)

I know that authors can be annoying no matter what you give them (for 
example, displaying text as graphics), but I think this would make 
being annoying far too easy.
