No, thank you.

I didn't first understand the big idea and only looked at the code
change per se. I apologize for that.

The problem that you went to solve was real and it led to a properly
implemented solution. You were not late from the party. Jason's code
change is derivative work of your code change. That's why his code
change has also your signed-off-by.

Thanks for doing awesome work :-)
