@Gordon, AFAIK, erasing can only be done on whole page(usually 4K). Therefore I would recommend to publish empty pages only. Otherwise it would happen too often, that data needed somewhere else, will be deleted.
For example, someone could store some data in a page, used partly by save(). Erase this page and you could come in trouble.
@tve, I see the problem with single firmware for all ESP8266-boards. Would Gordons list of unused flash pages help ? Would it be possible to create something like unused_flash, similar to saved_code in ESP8266_BOARD.py ?
