Does the L stand for lossy, or lossless? Or large, as in this case?
See I would think lossless is the one you have to specify. (Also, it stops being "large" when you extend this gripe to similar formats like AVIF and WebP.)
One L for Lossy, two for LossLess.
Does the one at the end of .JXL count toward the total? Nobody knows what it stands for anyway.
