First and foremost, each rectangle tool, Rectangle/Ellipse Select and
Crop, have its own tool options, so a certain Fixed: Size in th Crop
Tool will not affect the Fixed: Size in e.g. the Rectangle Select Tool.

Second of all, the problem you describe is actually solved (it was an
integral part of guigurus new rectangle tools redesign).

All Fixed: Size and Fixed: Aspect ratio entries have two modes,
user-overriden and automatic.

When in automatic mode, the numbers change whenever the default values
change.

When in user-overriden mode, the number are unchanged until the user
clears the textbox, in which case the entry goes back into automatic
mode. User-overriden mode is entered whenever the user explicitly enters
a value.

So, if you have explicitly entered a value for Fixed: Size, you are 
guaranteed that it will never change, until you clear the textbox and 
set the entry in automatic mode again.

Currently, only the Fixed: Aspect ratio of th Crop tool gets constantly
updated default values, namely to the size of the image/layer when there
is no pending rectangle, and the size of the pending crop rectangle when
there is one.

You can see whether or not a Fixed: Size/Apsect ratio entry is in
automatic mode or not; when the text is italic, it is in automatic mode.
  A normal font indicates user-overridden mode.

It is because of this automatic/user-overriden mode functionality that I
think what I suggested will work, but I am of course still looking for
other counter-arguments :)
