be changed to always fill up to 30 keys, so that the total numbers of keys is always constant?

I'm not sure what happens with the 1.5 and 1.6 GAEN API version, how many keys will be sent. But if it's more than 14, but less than 30, there might be some information leaked.

The iOS SDK does always send 30 keys:

Yes, it should! Therre is already an open PR for this: #192
