How to remove the notification "disable extensions in developer mode" in Google Chrome?

Question

Google Chrome

Starting with Chrome 33 , a "disable extensions in developer mode" window pops up on every launch:

How can I get rid of this annoying window without disabling the extension?
PS
To Google: where is the "I'm a developer, don't show me this warning again" button?

Answer 1

Batch patcher that removes this forced warning:
1. Copy the code below and save it in any text editor as, for example, DevWarningPatch.bat on the desktop
2. Close chrome manually so as not to lose the unfinished letter, for example , the batch file will end the remaining hidden processes by itself chrome is forced.
3. Right-click on the saved file and run it as an administrator to patch all installed versions of chrome (search is done through the registry or in the current folder).
You can also just drag chrome.dll from the portable chrome folder to the batch file icon.

Answer 2

While I found a way out in the form of installing the dev version of Chrome

Answer 3

if you pack and install the extension, the window does not pop up

Answer 4

I have switched to SRWare Iron so far, and extensions are not forcibly disabled there and, accordingly, no warnings are received in developer mode.
