I agree. When placing the view, make sure to use the sheet scale option. Then all views will scale at the same time when you change the sheet scale.
The sheet scale is a Solidworks system proprty. If you setup your drawing template
by starting an annotation note and linking the note to a property.
This will be based on the first view added. If all of the views scale is set per the drawing scale
If you need to change the sheet scale then you can RC on sheet ion the property manager
select properties and the scale can be adjusted or changed there.
Once all of this set none of the views should change on their own.
I hope this helps you.
I think you will have to put in an enhancement request.
