I see. Yes I think it's desirable. For me the desirable aspect is the 
distinction between text props and font-lock. Moreover I think the degree to 
which a thing makes sense also contributes to its desirability (if that makes 
sense).

And the undesirable aspects of the font-lock-update command the misleading 
side-effects: that it removed things and/or deactivated a minor mode. Put these 
things in other commands if they're going on C-x.
