Are you sure this is a bug?  It appears that sed behaves the same way:

Sed:

bash-4.2$ echo hello > tester
bash-4.2$ chmod -w tester
bash-4.2$ ls -l tester
-r--r--r-- 1 schorr ead 6 Jun 10 08:31 tester
bash-4.2$ sed -i -e s/hello/goodbye/ tester && echo YES
YES
bash-4.2$ cat tester
goodbye
bash-4.2$ ls -l tester
-r--r--r-- 1 schorr ead 8 Jun 10 08:31 tester

Gawk:

bash-4.2$ echo hello > tester
bash-4.2$ chmod -w tester
bash-4.2$ ls -l tester
-r--r--r-- 1 schorr ead 6 Jun 10 08:32 tester
bash-4.2$ gawk -i inplace '{gsub(/hello/,"goodbye"); print}' tester
bash-4.2$ cat tester
goodbye
bash-4.2$ ls -l tester
-r--r--r-- 1 schorr ead 8 Jun 10 08:33 tester
