First off, what's happening internally is that the label is used for the
element value -- which ends up becoming the *displayed* button value.
Label == display, value == value.
There are a variety of reasons behind this:
* To allow translations. If you have the value translated, then
the form attempts to translate submitted form values, leading to
issues.
* Ability to compare the submitted value against the label. This can
be an addtional sanity check to see that the form is being submitted
from the location you expect it, and is used internally by
isClicked() to determine if the button was clicked when submitting
the form.
* Ability to specify a different value than the label so that when the
form is submitted, you can have one thing displayed, and another
actually saved in your model.
If you don't like the implementation, you're free to create your own
implementation and drop it in using the plugin loader system. :-)
