If you have small hands and you are stretching for delet/backspace and a small kb allows you to hit this key without strain, it absolutely helps with strain on fingers.

I tried many things over the years including other ergonomics and gym etc.

Changing to a smaller split keyboard helped the most and I have not had pain since.

Granted mine has about 50 keys or so so it's not as extreme.
