I'm unable to edit. So quick update:

As per [1], the chrome.declarativeNetRequest.onRuleMatchedDebug is available only for unpacked extensions i.e. local extensions with a specific permission. So, I'm not sure under what context there will be a performance impact.

Anyone more familiar with internals of chrome and/or extension development in general can clarify if there are any downsides to enabling dev mode permanently.

A lot of people run with developer mode enabled permanently, especially extension developers, both professional and amateur.

I've seen no downsides myself.
