Localisation: plural notification variables

[xabirequejo]

Elk's notifications look like this atm:

  "notification": {
    "favourited_post": "favorited your post",
    "followed_you": "followed you",
    "followed_you_count": "{0} people followed you|{0} person followed you|{0} people followed you",
    "missing_type": "MISSING notification.type:",
    "reblogged_post": "boosted your post",
    "reported": "{0} reported {1}",
    "request_to_follow": "requested to follow you",
    "signed_up": "signed up",
    "update_status": "updated their post"

Only followed_you_count has variables for different amount of items.

Would it be ok to do the same with the other strings? Or would this break Elk?
Something like:
"reblogged_post": "boosted your posts|boosted your post|boosted your posts",
