Why unhelpful? Note, that you are already used to something, and 
different does not mean unhelpful. I would love to change colors 
(including transparency) so I could focus only on several tools. For 
me using alpha channel just to make something transparent is tiresome 
because I have to use more tools than I really need.

Well, one thing is history -- everything (in general) worked in the 
past -- why introduce cars when horses... etc etc etc :-)

The second thing is potential benefit -- and I believe less time spent 
on creating an image _is_ benefit. Note, that it will not introduce 
new features per se, it only could only change the way you work (if 
one wishes so). You can work with colors with color tools and you can 
only work with alpha channel with alpha channel tools. It is 
narrowing possibilities -- why not pick up brush, shape, pressure and 
polish a picture edges with transparency (as color)?

Wish granted -- simply use your finger (I assume you thought of glass 
painting because it is only good metaphor source for working with 
alpha channel in the first place).
