Currently maximum page size inside InnoDB is 16K. This is problematic especially if you have a lot of blob objects because at least part of the blob is always stored on single page and only ther remainder externally stored. This leads to situation where you can have only limited amount of columns as blobs.
Therefore, plan is
1) Increase the supported page size to 64K for COMPACT row format
2) Research if same can be supported for DYNAMIC row format
Currently, I do not have plans to support > 16K pages on COMPRESSED row format.
