Not just a small inconvenience—because there's no human readable way to tell the difference between v4 and v7 IDs, you have to guess and check whether or not the ID your server process is logging is a pre-conversion or post-conversion ID

The human readable way to tell the difference is you look at whether the third group starts with a 4 or a 7.

It is really easy to tell the difference btw. You will always see "4" or "7" in the middle.
