The chronological development of .22 rimfire was:
1857 .22 short 30gr bullet 3gr BP
1871 .22 long 30gr bullet 5gr BP
1880 .22 extra long 40gr bullet 6gr BP
1884 .22 long rifle 45gr bullet 5gr BP
The .22 LR when mated with the 40gr bullet found a balance of accuracy and small game power that pretty much made the extra long superfluous.
If you go much more powerful than .22 LR hyper velocity like CCI Velociter, you want the thicker .22 Magnum case between you and that much pressure. The Extra Long case is as thin as the .22 Short or Long, just longer in length.
