This is, actually, the oldest outstanding request on my list.
But for a long time I've shied away from changing anything that relates to the plurals issue. MK suggested that eaves could be treated the same way as throes - the plural as a common word and the singular as rare. But that approach has caused concerns for some forumites. If you're able to play the singular word you may well assume the plural is not playable, and would be infuriated to discover the next day that it was playable and common. I feel that it may be better to leave things be, rather than risk making them worse.
So there's quite a backlog of plural-related suggestions that I've been avoiding for some years.
