Trying to be persistent without being annoying - if you don't put them
in the data sheet, how will users get the info?  I see all sorts of
numbers in data sheets that are neither tested or guaranteed.  

"[1] Typical ratings are not guaranteed. The values listed are at room
temperature (+25 °C), nominal supply voltages.

[2] Pin capacitance is characterized but not tested."

I think if you omit power consumption info from your data sheets, you
will be disappointing a lot of users who need this info to begin
designs.  Even if user's designs are not running from batteries, they
need to be able to calculate requirements for the power supplies. 
 

It does not matter much to me since I don't think I can use the
Philips parts.  But I am sure I am not the only user who would need
the power info in the data sheet.  :)
