Blame the Battery ....

The bottom of most cylindrical lithium-ion cells has a plastic spacer, perhaps what you are referring to as being "gapped". However, I have seen many cell manufacturers, usually cheap ones. that stick the jelly-roll right into the can without any kind of spacer or protection other than the extra separator hanging off the edges of the electrodes.

And isnt it VERY likly that very high capacity ones that squeeze out every mm of space and even have bigger containers trying to get big numbers , will do exactally that?

There are 2 reasons i dont worry about having the Most capacity one they have today, they could have given up something for the capacity. like longevity or cycle ammount and robustness , or gone out of spec , and just can be damaged easier. by spec , mabey it is just common sence not some actual written law.
