There is a very valid reason why you might want to do this.

If all your ARM and interworking stuff is in assembler files then you 
can often write all your C code in straight Thumb and use Thumb 
libraries. That makes for a pure Thumb solution (except for a few 
lines of assembler) and means you have no interworking in thc 
libraries and C code. Result: potentially faster and smaller code.
