That’s taking advantage of auto-renumbering in markdown, so if they insert an entry they won’t have to change any others.

It is absurd if you mention that there are 3 and the cost of typing a 1 is the same as typing a 2 or a 3.

No wonder why modern software is a hot mess.

True, the cost of typing 1 is the same, but the cost of changing the numbering on all consecutive items if you break one up or add one or remove one is higher. It's just unfortunate Markdown used that syntax to indicate a numbered list in order to be "human readable".

My point is: why do you have automatic number in a list of 3 items that you mention in the text that there are 3 items? It is locked to 3! You said that in the text! And yet the commit removed the first indication of this 3 elements but not the second!

This is how markdown works. It is handy.
