First of all, it isn't all that hard to figure out whether a view is 
probably updatable (the presence of the respective rules would be a 
strong hint).  And second, if it's not, you get a fine error message 
and can move on.  So there is really no good reason for client tools to 
prevent you from using data entry forms on views.
