I wonder how many millions of man hours could have been saved over the last twenty years if we could have added semantic="false" to our tables rather than redesigning everything.

You can make them responsive easy enough if you override all the table styling. I've done that before.

For me it's the semantic meaning, a table is tabular data.

However, I must say that using CSS grid is just like the old table-based design days.
