Texture Sampler source, why not use shared by default?!

okay i think the title is pretty much self explanatory! i mean by default its set to “From texture asset” and as y’all know by changing it to one of shared ones we can use up to 128 textures if we want to, so its better! right?! or are we losing something by changing the sampler source to one of shared ones? if “From texture asset” is the limited one, when one might want to use this option? tnx!
