One of the "features" of the tiles design is that we do not specify that all tiles must be one filetype or another. This was deliberate and one of the reasons for this was to better support boundary situations. While JPG is preferred for imagery because of its relatively better image compression, PNG is suitable for the edges of a coverage because the alpha channel can be used. Because of this, I don't see any reason to change anything in the spec. (We'll see what the others say tomorrow.)
I acknowledge that we need to do a better job getting guidance like this onto geopackage.org.
At the SWG today we decided that there is no action required to the SWG, but that we should add some implementation guidance to geopackage.org. This ticket will stay open until that happens.
The question is whether we need to change the specification regarding tiles that are not as large as the specified dimensions. Two possible approaches come to mind:
Or we could do nothing.
